BT internet outage was our fault, says Equinix
Faulty UPS takes out 10 per cent of BT customers

Seems incredible to me that a brief power outage at a single location can cause so much disruption for so long.

Is there really that little resilience in the national network?

Yep, I read the issue was due to a Power outage at Telecity.

You read that in this thread

I may of also seen it in this thread, but I also read it on a few news sites.

Its possible, say an area lost its power and the UPS there kicked in, now this UPS sends back a message saying "hey I have lost power, save everything and then shut down", now if badly setup BT's network might of received that message and started to shut stuff down, hence the outage.

I am not saying this was what happened, but it is possible.

I think it wasn't all that bad - 90% of traffic still was routed ok, with 10% being affected. This shows the network was actually doing pretty well despite the outage. Obviously, you cannot expect 100% when a data centre as big and significant as telecity goes offline, which means both power and backup power fails - something extremely rare.

I could still access most sites, but the traffic was being routed via europe (tracert to here showed hops in amsterdam)

Is it just me or has BT died again???

Paul

It dieded

It's not just my imagination then

I cannot access anything, and TBB is very ... ... very slow and mostly times out.

My 57K6 Modem was faster than this.
