In the 1990's the MAEs and Gigaswitches would give us an unscheduled failure of a major exchange point on a regular basis, which let us demostrate our disaster recovery capabilities. With the improved reliability, i.e. the PAIXes haven't had a catastrophic failure, we haven't had as many opportunities to demonstrate how well we can handle a disaster at those locations.
Without creating an actual disaster, what if all the providers turned off their BGP sessions with other providers at a PAIX (or Equinix or LINX or where ever), both through the shared switch and private point-to-point links, for an hour. More than likely no one would notice, but then we would have some hard data. Individually providers have tested parts of their own network, but I haven't heard of any coordinated efforts to test recovery across all the service providers in a particular location.
There was a major power outage in Amsterdam on November 6th, which took down the power at 2 major housing locations (Nikhef and SARA), which house the original 2 AMS-IX sites, and lots of routers. Even though Amsterdam (and AMS-IX) is a major hub for european connections, most worked as usual, though some Dutch destinations has higher than normal delay and packet loss. /Jesper -- Jesper Skriver, jesper(at)skriver(dot)dk - CCIE #5456 Senior network engineer @ AS3292, TDC Tele Danmark One Unix to rule them all, One Resolver to find them, One IP to bring them all and in the zone to bind them.
