UPDATE 10:21amAccording to Entanet, ďThe problem has been confirmed on BTís side and they are currently investigating. We havenít been provided anything relating to the cause as of yet, but we will update upon receipt of this information. Unfortunately the BT systems remain down preventing us from looking into individual line issues.ĒUPDATE 10:43amThe official line from BTOpenreach is as follows: ďWeíre sorry that some BT and Plusnet customers are experiencing problems accessing some internet services this morning. This is due to power issues at one of our internet peering partnersí sites in London. Engineers are working to fix things as fast as possible.Ē Of course itís not just BT and Plusnet customers being affected.On the upside some traffic now appears to have been rerouted and customers are reporting an improvement, but there are still a lot of complaints coming in. We suspect this will be resolved fairly soon.UPDATE 10:52amThe power failure appears to have occurred at Londonís TeleCity data centre.

UPDATE 11:07amA private report from TeleCity, which was sent to certain providers earlier today and seen by ISPreview.co.uk, suggests that there was a power failure with one of their Uninterruptible Power Supply (UPS) systems at 8/9 Harbour Exchange (LD8) in London.The fault hit a key router (edge4-tch), although this was technically resolved at 9:15am. However the knock-on impact for ISPs like BT and their clients (consumers, businesses and other ISPs etc.) can often take a little bit longer to resolve (computer networks are complicated animals).Connections should be slowly getting back to normal.
UPS failure killed a key router.
Lots of engineers affected nationwide, too. Me being one of them !!
