UPDATE2 2nd Major Power Fault Affects UK ISPs, BT and Internet Services

After yesterday’s major disruption (here) we’re loathed to report that this morning appears to have started off in much the same way, with broadband ISPs from across the UK all reporting similar Internet disruption as a result of another possible power failure at a major London data centre.

Several ISPs are already pointing the finger at a power failure stemming from Telehouse North (specifically TFM10 as all the other kit is still powered). Meanwhile another ISP said they’ve lost all their London resilient interconnects to the BTWholesale DSL platform, although this has failed over to Manchester and so the impact was minimal.

The problem itself began after 7am this morning and once again it is affecting routing / DNS connectivity for multiple ISPs (i.e. you might have trouble accessing some websites and Internet services), albeit mostly those that use BT’s platform as a lot of ISPs connect through them. At the time of writing Telehouse are still working to restore power.

We should point out that yesterday’s fault stemmed from TeleCity, not Telehouse (i.e. different site), although it’s easy to get the two confused. No doubt questions will be asked about why this has happened twice in a row, albeit at different sites. Here’s a summary of some ISP updates.

UPDATE 10:06am

We’re getting tentative reports that the situation is now being resolved, although like yesterday it could take a couple of hours before everything returns to normal. In some cases you might be able to get rid of the problem by power cycling (rebooting) your router, but don’t do this repeatedly as it may harm your service speeds.

UPDATE 12:29pm

Telehouse Europe has finally issued a brief statement on the matter: “We are aware that there has been an issue with the tripping of a circuit breaker within Telehouse North that has affected a specific and limited group of customers within the building. The problem has been investigated and the solution identified. Our engineers are working with our customers on the resolution right now. We will release updates in due course.”

Some equipment will need to be replaced, although most ISPs have already managed to move traffic around the problem area.
