The official story was memory fault of some kind, not specified as being corruption, hardware error, fragmentation or something else. Outage was 3 hours and reports have been posted stating that it not only affected their broadband business but also their company/commercial customers. No further details have been released to the swedish ISP community anyway, it's likely that they're still investigating and might or might not release further details. I'm also curious. -- Mikael Abrahamsson email: swmike@swm.pp.se

Mikael wrote about memory shortage. I have heard the same -- though not from press contacts but from staff. It was worded (but in swedish, so bear with my translation): "The official reason is 'memory shortage'. I do believe it is correct." There have been words in the grapevine about not going for full memory on line cards and RP, for "optimisation reasons". Sounds like a fine recipe for promoting cascading failures from a fragile base config. -- Måns Nilsson Systems Specialist +46 70 681 7204 KTHNOC MN1334-RIPE I represent a sardine!!
