It is possible. I think it's exceptionally unlikely.
The one bit of information we have suggests that the root cause was a networking issue, which suggests SPOF.
- leoc 16y agoIf I had to, I'd guess that AWS's messaging/monitoring/control infrastructure is likely to be the SPOF, as in the 2008 outage: http://status.aws.amazon.com/s3-20080720.html http://status.aws.amazon.com/s3-20080720.html It's an obvious weak spot in the independence/isolation of AWS' nodes, and it would seem to be the one most likely to cause failure to reach across more than one AZ. (Apart from a stampede from one, affected AZ to others perhaps.)
