Intermittent Internet Connectivity Woes Strike Virgin Media UK UPDATE8

Monday, Apr 27th, 2020 (8:35 pm) - Score 39,408

Customers of TV and broadband ISP Virgin Media UK have this evening been affected by a seemingly intermittent problem with their national internet connectivity, which the operator initially claimed to have resolved only for the issue to return again and again. Other ISPs, Virgin Mobile and Ethernet services have also been impacted.

The problems appear to have started at just after 5pm and tend to result in a mix of issues, most commonly slow performance and a loss of internet connectivity approximately every 5-10 minutes (sometimes going offline for a similar length of time). Initially a spokesperson for Virgin Media said that they were “currently investigating an intermittent broadband issue that lasted for a very short period of time earlier this evening” but that “services are currently back up and running.

Despite that claim the fault soon returned and the operator’s teams are continuing to investigate the problem, with the spokesperson adding that they will “work flat out to fix it” and “apologise for any inconvenience caused.” The issue, which appears to be affecting people right across the country, has now been on-going for several hours and we await a further update.

Faults as uneven and widespread as this one tend to be quite rare in the industry, most often resulting from a bad configuration or key piece of faulty hardware. Nevertheless we’d usually expect such issues to be resolved first time – with only a short period of disruption – and not for them to return on three or more occasions.

Sadly such operators are rarely forthcoming with much detail during these events and so we usually only get the answers from other sources after the fact. As an extra bonus some of the operator’s Mobile customers (currently based off the EE MVNO platform, albeit soon to join Vodafone) appear to be suffering from similar issues with their call and data connectivity.

UPDATE 8:48pm

A spokesperson has just issued the following update, which doesn’t really tell us anything new: “Our teams are urgently looking into the issue and will work flat out to fix it the moment the problem is fully identified. We know how frustrating this is and we apologise.”

The operator has also established a dedicated web page for the fault (it’s not often we see them doing that). Some additional feedback has further suggested that this may also be affecting their business Ethernet clients.

UPDATE 9:06pm

A quick look at some feedback from customers of Sky Broadband, BT and TalkTalk suggests that they too also saw some disruption around the same three periods, albeit seemingly not to the same level as Virgin Media (i.e. the complaints have not been to the same scale or volume). The issue at BT was however much bigger than the other two, but that may just reflect the operator’s size as the biggest ISP.

We know that some of these operators do make use of capacity links from Virgin Media, although equally the issue could be further up the routing/peering chain. At present there are three clear peaks of related complaints at around 5:30pm, 6:15pm and 7:12-7:29pm.

UPDATE 9:20pm

Feedback coming in suggests that a fourth outage has just occurred, although we don’t yet know if this one is going to be as big as the others or if it will be much more location specific. Customers of BT, Sky Broadband and TalkTalk are also reporting some problems at exactly the same time, just like before.

UPDATE 9:37pm

Please note that due to high interest in this topic I’ve had to enable strict caching on the article, thus if you post a comment then don’t expect to see it appear immediately.

Back to the topic. We haven’t been able to reach all of our usual sources to confirm yet, but we know that the issue is definitely not a capacity or usage problem. The technical fault, as suggested earlier, appears to be occurring further back on the network (central/core).

Virgin’s website is also running very slowly and not at all for some people.

UPDATE 28th April 2020 – 6:35am

After the last 9:20am outage we detected a further two at around 11:04pm and then 12 midnight. The fault hasn’t been seen since then, at least not to the same scale, but past midnight most people will have gone to sleep and thus detecting a re-occurrence becomes much harder.

The fault itself is known to have been impacting Liberty Global’s operations in other EU countries, which shifts some of the blame further down the line. Sadly we haven’t received any further updates from Virgin Media and so will be watching closely this morning to see what happens as people wake up.

We note that Virgin’s location specific Service Status page is currently reporting an estimated fix time of 9:05am this morning, which may vary for other parts of the country but it seemed consistent across several postcodes.

UPDATE 28th April 2020 – 8:50am

In a status update posted at 8:20am the operator said: “The issue was fixed in the early hours of this morning and it was not caused by a spike in usage or a lack of network capacity. We know how frustrating this was for everyone and we’re really sorry for the disruption caused.”

After such a huge level of disruption we don’t think it’s acceptable to just sweep this under the carpet (a classic trend among major operators). We want to know what actually happened and will continue to dig until we find out.

Meanwhile there are still an above normal level of sporadic complaints, much like we saw yesterday before the main peaks of the issue (i.e. a much smaller number of people reporting the same issue). Virgin’s support teams are advising a router reboot, but then they initially did that yesterday too.

UPDATE 28th April 2020 – 11:42am

Data provided to us by ThousandEyes has helped to track and trace the outage, or at least most of the related disruption, back to Liberty Global’s related UPC Broadband network (AS6830). You can see this a bit better with the visualisation below.

NOTE: The numbers in the circles reflect events detected on each link.


The AS6830 network operates a lot of key peering arrangements with Content Delivery Networks (CDN), as well as other major UK and international networks (e.g. Akamai, Level 3, Telia, Cogent and about a thousand more like them). The visualisation shows that connectivity was disrupted to a number of those significant destinations.

We now have a better understanding of where the issue occurred and why there were so many outages, although I’ll reserve writing about the detail of this until I can get some concrete confirmation on the problem itself.

UPDATE 28th April 2020 – 1:17pm

A spokesperson for Virgin Media has just told ISPreview.co.uk: “Our investigation is still ongoing but we believe the issue to have been caused by a technical fault within our core network which resulted in intermittent connectivity issues.” We of course now know, thanks to the previous update above and other sources, that this “technical issue” almost certainly relates to router (peering) configuration problems.

    Thought I’d point out that this is still ongoing. Just cutout again at 9:18 in North London, on what I believe is the Finchley headend.

    Can also confirm that the Virgin media gateway that I connect to is still operational during these outages. It appears that it’s related to their core routing infrastructure.

      I see exactly the same in my own ping-logs. In fact I see similar “packet-loss storms” of around 3 mins or so, going back weeks and weeks, but more usually in the early hours.

      Occasionally they hit daytime too. They’ve only now become obvious due to the sustained network usage when WFH.

    2. Avatar photo mark-m says:

      It’s slightly early days, however I’ve not had a single packet dropped in a continuous ping test to a public DNS server in more than 24 hours. I’ve not seen that level of ‘connectivity reliability’ for weeks.

      I do wonder if there was a long term problem lurking somewhere in VM’s network that finally got fixed.

    1. Avatar photo Alex says:

      Whilst I agree on the premise of a small upgrade to fix issues down the line with capacity, demand, etc. I can’t imagine VM scheduling this for 5pm. Surely that’s an overnight job when peak times are over?

  12. Avatar photo Scott says:

    I’ve gone down at :16 past each hour apart from 8:16. It seems to last for around 5 minutes before partial service is resumed where I can access some websites but not all. Takes another 10 before all issues are resolved.

    Hope they manage to get this fixed before tomorrow or WFH could be fun.

    I’ve had three broadband failures this afternoon. To make matters worse any attempt to get some information from the service status page results in failure with a “Oops something’s broken” message.

    And oddly I also struggled at times to get internet access from my Virgin Mobile phone with the signal strength indicator of H or H+ at best showing instead of the usual 4G. Was this a sign that the EE mobile network couldn’t cope?

    1. Avatar photo Roger_Gooner says:

      I had a fourth outage just after midnight. In all my years of cable broadband since 2001 with Cable London, Telewest and Virgin Media I’ve never known such a widespread problem.

  26. Avatar photo M says:

    As usual, all the other ISPs seem to have redundancy in place to avoid VM’s network. What redundancy has VM got? Has VM ever had redundancy? From a almost two decade old customer. I can categorically state: no. Does every other ISP have IPv6 yet? Pretty much. Does VM? no. Yes, VM have a shed load of bandwidth to haul but so do BT and they’re managing fine. It’s time to redirect money from the Ivory towers and redirect it to the NOC minions for salaries and assets to give us a proper network. Going to enjoy contract negotiations in a couple of months.

    We are on their 1Gig service. Been intermittent since Friday. Dropped twice on Friday and once on Saturday and quite a few times tonight. Since January we have been intermittently but frequently dogged with this very issue, outages, performance problems and only being able to access a subset of websites. Tonight is obviously more widespread though. Hopefully they can fix it for good and for everyone.

    Does anyone understand why the mobile internet goes down at the same time as cable? I don’t understand the technical basis for that given their mobile service is MVNO on EE.

    1. Avatar photo Blueacid says:

      My guess is that Virgin Media have struck a deal with EE whereby EE hand customer internet traffic over to Virgin Media, then VM deal with their customer’s traffic separately.
      If VM are therefore suffering a core network outage, that’ll knock out their mobile customers internet as well, but EE mobile users wouldn’t be affected — in fact, they might notice a speed increase due to the sudden absence of any VM customer traffic!

      Check the different types. Virgin Mobile are an Enhanced Service Provider / Thick MVNO. They don’t simply resell EE.

    1. Mark-Jackson Mark Jackson says:

      Sometimes a more location specific problem gets confused with a wider, but separate, fault and of course there’s no easy way for consumers to tell the difference. Other times a major fault can start small but then rapidly escalate as any changes in the environment propagate through a network.

      In short, the times you see reflected in the news article reflect only the extreme peaks or spike of significant consumer gripes that rise well above the rest.

Each time a full re-boot (power down, disconnection of coax for 5 minutes before re-connecting and power back on) was required to get any connection. Noticed Wi-Fi goes first. I have the latest router. No error lights on the box so look ok, but no connection. I Will report back if any further loss.

      How long did you leave it before doing this rather comprehensive “turn it off and on again”? I have just left it all switched on for the 5-10 minutes it is down, and then all is fine – no reboot has been needed. If you’re rebooting as soon as you notice a problem then most likely the reboot is finishing at about the same time as you would have been back online anyway.

      Just been contacted via Twitter and told to reboot router! Informed them of how many times I had done so and how much more than power off I had done.

      work on a project, throw in a load of 1 year certs, project ends, contractors leave, 4 months later the service stops as no one bothered to utilise some kind of system to remind anyone to update the certs, despite me stating its needed.

      rinse and repeat.

      How can we even begin to find out who the perpetrators were when OFFTOSS throw their weight about and stop ANY discussion of this particular subject? This is why Brian Rose has started his free platform so that things can be discussed without the fear of heavy-handed bureaucrats deciding what THEY want the public to know about. We are capable of making our own minds up. I saw someone buy a copy of The Sun the other day, but it wasn’t up to me to tell him what to read. (Poor man).

      “How can we even begin to find out who the perpetrators were when OFFTOSS throw their weight about and stop ANY discussion of this particular subject?”

      In fairness I can’t see how that’s relevant to finding out who the perpetrators were. Locals with information need to contact the police and the police then do their job. A bunch of people whittling on about conspiracy theories online, which will only fan the flames of violence, seems likely to do exactly the opposite of helping.

      But in any case, none of this is relevant to the above topic, so let’s all move on.

    “it was not caused by a spike in usage or a lack of network capacity”

    This is PR speak for “human error”, is it not?

    It implies they knew what the fault was, fixed it and failed.

    Also, the little yellow button that says “throttle everything” (usually active 5-10pm) wasn’t lit up.

    Unless there is actual gibbon wondering through the LG datacenter hitting all the “throttle everything” alarms. Now THAT would be an awesome failure root cause.

    1. Avatar photo Ferrocene Cloud says:

      Some sort of human error, or some partial failure. I’d be more inclined to think the latter at this stage, especially as the issue seemed to start around 5PM when most operators would not make changes that had such potential impact at that time.

      Looking as my connection graph from last night, I can see 8 separate outages of around 10 minutes each over 12 hours. That would be more common of a link/node/line card flapping or crashing in my experience.

      In some ways stuff that’s going up and down is far worse than something that’s failed outright, because it makes it much harder to locate it, and to determine if it’s a one off outage or something which needs corrective action. You can even have cases where failed hardware reports there’s nothing wrong, and you then spend a lot of time chasing down exactly where the problem is. Until you know exactly what’s gone wrong, you can’t fix it – fixing it is usually the easy part!

    2. Avatar photo CarlT says:

      Well, no. It implies they know what the issue wasn’t. If they said the issue wasn’t related to the outbreak of World War Three or SARS-COV-2 mutating into digital virus it wouldn’t tell you much about what the fault was.

      Capacity issues don’t manifest as that fault did, and given the media fixation with whether the Internet can handle the demands placed on it during lockdown it was a valid statement to make.

    I spoke to a reporter at The Register this morning and they are interested as well as this being in daily newspapers. we should expect a fuller statement from VM which The Register would chase. Normally those things take some time to prepare and go before the legal teams, should they choose to do it.

    Local losses in connection are one thing, but national scale outages present risk and can be scary, if you consider the current world status and possible attacks on our core internet trunks and providers. Not saying it was an attack, just it would put my mind at ease to know that we had the correct amount of resiliency, redundancy and security in our nations services.

    Ah this explains what was happening! I thought it was a config issue because my router kept switching over to the backup sky ADSL connection, whilst the virgin modem was still locked on a signal.

    “The AS6830 network operates a lot of key peering arrangements with Content Delivery Networks (CDN), as well as other major UK and international networks”

    Im unsure of the relevance of this when Virgin Media almost certainly has caches from all the major CDN’s embedded within its as5089 network, with the parent as6830 providing connectivity to external destinations via its peering and transit relationships.

    Is there any other evidence to support the assertion that this issue “almost certainly relates to a router (peering) configuration problem(s)” ?

    1. Mark-Jackson Mark Jackson says:


      But to answer your question, yes there is, from several credible sources, but they’re not people I can quote directly. I have to balance what I can say with protecting where the information comes from. Everything points to peering router configuration problems. If you know something different, which I doubt, then please do constructively share or help rather than criticise.

      While not meant to offend, I am unsure how better to describe journalism which presents unsubstantiated conclusions without even quoting the “other sources” that you subsequently clarify to be “credible”.. unless it was intentional “fake news”? 😉

      The only evidence offered to back up the claim that the “technical issue almost certainly relates to router (peering) configuration problems” is “thanks to the previous update” consisting of a single diagram based on “Data provided to us by ThousandEyes”… which appears to show some test hosts within Virgin Media/Liberty Global’s networks failing to be able to reach some external destinations outside of their network.

      So although understandable why it may be tempting to conclude that the issue must therefor be at the border of VM/LG’s networks, aka their Peering Routers, all this appears to show is that there are issues somewhere between the test hosts and the external destinations..

      Is there, for example, any data to show that there was no issues with traffic between the test hosts which would actually lend credibility to your assertions that the cause of the issues is “almost certainly” the peering edge rather than the “core network” as you quote Virgin Media as having advised you? 😉

      Either you’re trolling (most likely) or just new to this site. Regular readers will be familiar with our long established trend of leaking major Virgin Media announcements (same for other ISPs), and often long before they’re made public. None of that would be possible without established sources and contacts within the industry, which have been built-up over 20 years. If you don’t like it, then don’t visit.

      While I won’t be adding to the overall purpose of the comments section for the article, I do feel it appropriate to call out that Mark is quite simply the absolute opposite of lazy and for me and many others, is a great source of information & trust.

    In the outer limits of wild west London VM have been intermittent for weeks and some would say years. The start of this latest appalling service period was just before lockdown when VM service diappeared for three days, they of course said three hours. If my expensive TV package and boredband not working for three days I know how long! Outages almost every day since, many hours yesterday evening 27th Apr 2020 and hours this evening 28th April 2020. Fortunately three did a fantastic deal recently unlimited data for 15 pounds per month for next two years. I am saving up my pocket money for the 5G mobile (actually waiting for Nokia) and improving coverage then cut myself three from all the physical connection %$&*. I have no loyalty to any provider they just need to provide a reliable service and I might stick with them. Anyone know how to get Discovery HD without TV package? Goldrush!

    So I’ve been having issues with VM Broadband for about 3 weeks and was unaware that this was an internal core issue until today after reading this article and the comments. It started with the connection getting increasingly bad one evening until my Hub just disconnecting completely and not connecting for the rest of that day. I called tech support and they sent me a replacement Hub. I didn’t bother to change the Hub when it arrived as it seemed to be working on and off again and didn’t expect a replacement to make any difference. One day probably a week ago it was very bad so I decided to try the new Hub but as expected the problems have been the same with connection drops constantly in intervals throughout the day and again one evening the Hub completely disconnected. I’ve tried not to bother them unnecessarily by troubleshooting with all their ‘tips’ such as restarting the router and running the online internet test but the problem has stayed the same. Running an infinite ping test shows frequent drops and times out. I called them again today and the guy on the phone was pretty rude and insisted that I “let him finish” while he tried to walk me through all the obvious things I’ve tried a million times. He did finally agree to send an engineer out but rudely stated that if no fault was found I would be charged…. I’ve since come across this article and now understand that this is most likely an internal issue with VM but why don’t they just tell this to customers on the phone? I would completely understand and be more than patient. I’m now worried that this engineer will be wasting his time and they will charge me for the call out…

    Been withVM since beginning and very happy but recently intermitent outage affects numerous gadgets My MacBook hubby’s windows, sonos wifi sound system, Hive heating and apple phones. Keep being told all is well but if this keeps up I will be forced to look elsewhere. Since they changed the service is poor and unhelpful. Hard to get hold of, definately NOT the company it once was

    It’s been happening for at least the last 2 weeks where a webpage just freezes and refuses to update and when loading a new web page it quite often times out only to load it next time of asking. It’s not like web pages take long to load when it decides to load them but there is a lot of latency.

    There is definitely something continuing to be wrong with the Virgin Media web infrastructure.

    Get it fixed or users will be leaving in droves.

    Still happening to me (Surrey-Hampshire area, Windows 10 PC).

    Zoom says “your internet connection is unstable” every few minutes.
    “Three” wifi calls on iPhone typically go permanently silent (without actually disconnecting) after a few minutes (this does not happen when using 3G/4G).
    Much Microsoft software (Office365, Edge browser) claims I am offline / not connected to the internet then the page typically refreshes itself after a couple of seconds (without user action needed). I originally thought this would be a Windows 10 issue: maybe both are at fault?

    I’m with TalkTalk and have been having an issue for about a week now which sounds exactly like the issue being described near the top of these comments, i.e. I lose Internet connectivity for a few minutes at around 15-20 minutes past every hour. I’m in Cambridgeshire in case that’s relevant.

  73. Avatar photo Christian says:

    Happening to me this week with Virgin media. Called Monday, got sent a new router which arrived Wednesday. Still, internet kept cutting off. They advised they’ll send someone next day, next thing they send a text message to cancel that as they’ve now “fixed the problem”. Friday, lost internet connection again and now on hold for half an hour.

    I’ve been getting this for almost a year. This ‘upgrade’ has actually made it worse.

  77. Avatar photo Robin says:

    I have started having an issue with dropping out for two weeks now. I have been given a replacement Hub 3 and that has lessened the dropping out but it is still happening. VM must be aware of this, so why can’t they put their hands up and tell us. If VM is upgrading services for the benefit of us, despite the short term issues, then so be it. But please tell us as many are spending time and money investigating/replacing downstream equipment (e.g own router/hubs). I work from home as many currently do, and so can’t afford the time or money to keep investigating. If there is nothing we can do to fix the issue, then at least be adult enough to tell us so we can at least know, this will all end soon!

    Our broadband went down 2 weeks ago, first only for a short time, now it’s all day every day sometimes for hours went down at 18:00 last night still down at 6:30am this morning, Virgin tv also being affected, we’ve were given a fix date 28/9/2020 didn’t happen now today 2/10/2020 don’t see that happening as they still have not identified the “appliance they say is causing noise to affect the fibre. I have had to break company policy during Covid 19 to stay working from home for the past 2 weeks and will be longer. I’ve asked for them to get a report from an actual Engineer working on this to find out if they are close to finding the source of the fault and I am getting nowhere. So we have no broadband and I have no choice but to break company ruling at the moment by working in the office
