For DynamoDB, I'm not sure but I think its covered. https://aws.amazon.com/dynamodb/sla/. "An "Error" is any Request that returns a 500 or 503 error code, as described in DynamoDB". There were tons of 5XX errors. In addition, this calculation uses percentage of successful requests, so even partial degradation counts against the SLA.

From reading the EC2 SLA I don't think this is covered. https://aws.amazon.com/compute/sla/

The reason is the SLA says "For the Instance-Level SLA, your Single EC2 Instance has no external connectivity.". Instances that were already created kept working, so this isn't covered. The SLA doesn't cover creation of new instances.
