Was looking for this post. We've been having very strange issues since ~11:30 AM ET in us-east-2. We have a DB instance that became suddenly unresponsive to queries even though we could still shell in, almost like a disk died or something. Rebooting the instance has been hanging for >30 minutes. Seeing a smattering of other things not working as intended as well.
