We re-solved the issue and everything is operational again.

One of our reverse-proxy instances scaled in ungracefully which caused routing errors.
After manually terminating it, the services recovered.

We saw elevated errors from 16.01 UTC to 16.48 UTC. A good part of it was recovered by internal retries, but we can't be certain right now to not have lost some events.

We will analyze and provide a long term fix so that this won't happen again.

Our apologies for this as we were not able to capture all data during this time.
