I have noticed that Level(3) misconfigs/outages seem to happen more frequently than with most other Tier 1?s. Am unsure whether or not this is a mis-statement, but based on NANOG posts, Level(3) [AS3356] seems to show up more often with issues than say Sprint [AS1239]. Is their any one (or any coporation) that keeps track of outages such as these? Would think it might be a good thing to know for proper mulit-homing relationships to minimize the type of outage that Yahoo faced?
