Amazon claims the issues only affected 1 AZ.
From approximately 12:51 PM PDT to 1:42 PM PDT network packet loss caused elevated EBS-related API error rates in a single AZ, a small number of EBS volumes in that AZ to experience degraded performance, and a small number of EC2 instances to become unreachable due to packet loss in a single AZ in the US-EAST-1 Region. http://status.aws.amazon.com http://status.aws.amazon.com
So.. are we to believe that Instagram, Vine, etc. are not properly architected for multi-AZ failover? Or is there more to this than what Amazon is reporting?
Bottom line, why did these apps have any significant downtime at all?
- thezilch 13y agoPotentially, they do not have multi-AZ ELBs and only thought to have their EC2 or similar instances in multi-AZ. Or they don't have proper tuning of their DNS to stop routing to failing ELBs. Or... Amazon is unaware or not making us aware of the side-effects that their subnet outages tend to have on the overall network in a region.
