We just had a power outage in Ashburn starting at 10 pm Sunday night. It restored at 3:40am ish, and I know datacenters have redundant power sources but the timing is very suspicious. The AWS outage supposedly started at midnight
Even with redundancy, the response time between NYC and Amazon East in Ashburn is something like 10 ms. The impedance mismatch and dropped packets and increased latency would doom most organizations craplications.
