Above.net off the air

Anyone who was in the know care to comment on what caused Above.net to seemingly go off the air for over an hour on 2/25/1999? I checked the above.net network blocks at all the public exchanges, all the route servers, and there were no blocks being annouced from above.net for a while, and then the network entries came back. http://www.iad.above.net/traffic/core1.iad.above.net.pos5-0.html seems to bear out the fact that there was traffic loss. Having an entire major AS just vanish seems to be an interesting operational item from the pov of people buying transit or having equipment colo'ed with them. /vijay
