Most large exchange facilities in New York seem to have survived on battery and diesel power, and I don't believe the outage stretched as far as Virginia (where it might have stood a fighting chance of impacting some high concentrations of network operators).

So probably not related to the power outage.

Sorry, it also says on the MS site ... "102 GB of content" then goes on to say "Content created around the clock. Approximately 4 GB of new and updated content published daily". That would mean that every 25 days it would create or update the same amount of content that is currently on the server. Surely this isnt correct?
