us-east-1 and us-west-2 regions are experiencing networking issues and it also having an affect on a number of other cloud services that rely on those regions.

The number of AWS services this is affecting is growing and will probably affect the majority of their services to some degree.

It isn’t a full network outage, but instead a sporadic one (too much load?). As in, one ECS task will be able to register itself with the application load-balancer, while another one will not. If you have an automated environment, this is causing rolling failures right now.

This is impacting one of my clients greatly as those are their primary and DR regions. We are considering deploying DR in a 3rd region, but it could take hours to replicate their database.
