The fun part of this emergency maintenance in the northeast USA was that even folks who are multihomed felt it: Level3 managed to do this in a way that kept BGP sessions up but killed the ability to actually pass traffic. I'm not sure what they did that caused this, or whether anyone but northeast folks were affected by it, but it sure was neat to be effectively blackholed in and out of one of your provided circuits for a while. Also, in the northeast, they managed to make it quite a bit more than a 30min outage for many people; they even slid hours outside of their advertised emergency window. I do applaud them for what I can only assume was a *massive* undertaking: emergency upgrading that many routers in such a short period of time. -- Jonathan Towne
