Correction: Classic analysis is operating normally, we were misreading some metrics when we made the last update. All systems should be operating normally at this time.

We tracked the issue down to ECS services not being placed correctly after the underlying EC2 instances were rotated (as they are every night). The website and Platform analysis is operating normally now. Our Classic analysis hasn't recovered yet, and we're working to address that now.

After restarting some services, the site is back up and analysis is occurring normally. We're continuing to monitor and trying to identify a root cause.
