Aren't multiple availability zones impacted though? I don't get how Heroku can be so widely impacted if its not for the fact that multiple Availabiltiy Zones have been impacted.
The power issue only struck 1 of the 5 zones in US East (Virgina)
I can't speak to why Heroku was impacted as much as it was. It could be that they have single points of failure, or run at a utilization level that makes losing a single zone difficult.
