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..

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.
