High Order Failure - London PoP
Looks a lot like there's a 'high order failure' on the BT network in their London PoP, trace below.
If the problem is isolated to London, it might mean that northerners will avoid the problem and be routed through the ManIX PoP. Anything hosted in London though, or anyone in the UK who's connectivity will traverse a London PoP/LINX connectivity is screwed!
