Istr major resource unavailability in US-East-2 during one of the big US-East-1 outages because people were trying to fail over. Then a week later there was a US-East-2 outage that didn't make the news.
So if you tried to be "smart" and set up in Ohio you got crushed by the thundering herd coming out of Virginia and then bit again because aws barely cares about you region and neither does anyone else.
The truth is Amazon doesn't have any real backup for Virginia. They don't have the capacity anywhere else and the whole geographic distribution scheme is a chimera.
This is an interesting point. As recently as mid-2023 us-east-2 was 3 campuses with a 5 building design capacity at each. I know they've expanded by multiples since, but us-east-1 would still dwarf them.
Makes one wonder, does us-west-2 have the capacity to take on this surge?
