UPDATE Broadband ISPs Hit by Slow Speed, Latency and Connectivity Fault

A number of UK ISPs (Zen Internet, iDNET, Merula etc.) are this afternoon reporting a “nationwide” disruption to their DSL (ADSL / VDSL2) based broadband connections, which may be causing connectivity problems and bouts of slow service speed or high latency for some customers.

The problem was first spotted at just after 11am today and an increasing number of providers appear to be reporting it. Apparently the cause of this fault has now been identified and a fix is currently being developed, although nobody has been able to offer a clear ETA for the fix.

Take note that this issue appears to be separate from the fibre optic cable break that has been causing problems for Sky Broadband’s subscribers in the North East of England since yesterday.

iDNET Service Status

Our Suppliers have identified an issue causing slow speeds, packet loss and intermittent connectivity to some broadband customers Nationwide.

Investigations are ongoing but an ETA for fix has not yet been advised.

Further updates will be posted as soon as we have more information.

Zen Service Status

We have seen subscriber drops and had reports of packet loss and intermittency for a portion of our DSL subscriber base.

Zen regret any inconvenience this may cause.

UPDATE 4:20pm

Services are now returning to normal after the fault was fixed, although some users may need to power cycle (reboot) their broadband routers in order to re-connect.

UPDATE 12th October 2017

Zen Internet has kindly offered a little bit more detail on yesterday’s problem. A spokesperson told ISPreview.co.uk, “We noticed packet loss around 11am yesterday – 11th October 2017. We quickly diagnosed that one of our backhaul providers had experienced congestion issues within their network. The cause is believed to be a fault affecting resilience within their core network. The fault was resolved by the backhaul provider within the agreed service level fix time of four hours. We are continuing to work with the provider to understand the root cause of this issue and if there are any learnings and improvements that can be made from it.”
