Realistically, it's at least in part because everyone defaults to the East region. So it's the most crowded and demanding on the system.

- jey 14y agoYeah, it's got to be much larger than the other regions, so it makes sense that we see more errors. Since error_rate = machines * error_rate_per_machine.
- nasmorn 14y agoThe whole region is down, you just calculated the chance of at least one machine having an error.
- jey 14y agoNo, I calculated the error rate for the region. If us-east-1 has 5 times the machines (or availability zones, or routers, or EBS backplanes, or other thing-that-can-fail) as us-west-1, we would expect to see us-east-1 have each type of error occur about 5 times as often as us-west-1.
- obeattie 14y agoYep, according to the most recent estimate I saw[1], us-east was more than twice the size of all other regions combined. [1] http://huanliu.wordpress.com/2012/03/13/amazon-data-center-size/ http://huanliu.wordpress.com/2012/03/13/amazon-data-center-s...
- peterwwillis 14y agoIt's not just because it's crowded. Everyone I know who's worked in that DC hated it. Aside from that, storms regularly knock out the grid in NoVa.
