As of 4.22pm PST, AWS has resolved the outage on their side. They did mention that instances that have not recovered so far will need to be manually recovered. In the past few hours, Instaclustr has recovered over 90% of the impacted nodes and only a few remain. We'd be resolving this incident and communicating on the respective customer tickets.

At approx 4.35 PST today, AWS has identified a power outage that caused issues launching EC2 instances in the US-EAST-1 region (US-USE1-AZ4). This issue will impact existing clusters and also new node provisioning in that region (instance store & EBS backed). Other availability zones in US-EAST-1 remain unaffected. AWS has been working through this issue for the past few hours and power was restored at approx 06:51AM PST. The latest AWS update (as of 08:02AM PST) says that the instances will continue recovering. Instaclustr Support has identified the list of nodes that are impacted by this incident and will take remediation measures as necessary to recover the nodes. This incident should have no impact to your application if you have proper fault tolerant mechanisms in place (e.g RF3, querying at quorum etc.).
