I think this is old news. There was a cover story back in 1996 time frame on Mae_east. We have to ask how likely is this with many of the top backbones doing private peering over local loops, how much damage would occur if an exchange point where hit?
well recent issues have suggested an exchange can cause short term issues at least, for a longer outage i dont think we have an example.. in the short term flap dampening causes unreachability and circuits hitting capacity prior to a reroute by the noc are big problems but these may be solvable (or worsened) if an outage were to persist..
It depends which exchange point is hit. There are a couple of buildings in London which if hit would have a disasterous affect on UK and European peering.
Europe would reroute, UK would suffer.. but this comes back to the regional effect
What about fibre landing stations? Are these diverse enough? Again, most of the transatlantic fibre (for the UK) appears to come in near Lands End.
Hmm, I know of multiple landings including lands end... so it is diverse, but the sheer bandwidth down one cable is very large, an outage would be noticable. Steve
