As @lizthegrey points out, "making changes to DNS to mitigate" appears to be homed through us-east-1; using @awscloud for DNS looks like it may be A Mistake You Should Avoid as a result. This is important, concerning, and more than a smidgen disappointing as a customer. https://t.co/V8UeCe7EgO

Summary of the AWS outage - decidedly lacking on details, as is typical for Amazon. Seems like a cascading failure along multiple vectors, with design assumptions about availability that didn’t hold water. https://t.co/vR5zk2sGOD

AWS with their post-mortem on the US-East outage on Tuesday. Critical internal network was overwhelmed, which cascaded into dependent control plane, monitoring, and customer support systems, dominoeing into RDS & EC2 deployments, then all hell broke loose.https://t.co/STPmRJAXq6

The @awscloud explanation of their outage earlier this week has been posted. https://t.co/5ZPyPtf7am

The AWS outage, explained: "At 7:30 AM PST (on Tuesday), an automated activity to scale capacity of one of the AWS services hosted in the main AWS network triggered an unexpected behavior from a large number of clients inside the internal network." https://t.co/R3VbIgz5MA

interesting nugget: if you were multi-region but needed to push DNS to swap regions, you were SOL. "Route 53 APIs were impaired from 7:30 AM PST until 2:30 PM PST preventing customers from making changes to their DNS entries, but existing DNS entries were not impacted" https://t.co/LTvSL3kezg
