Our new "redundant" Amazon database quarantine system was down today for about 30 minutes from 7:31am PST to 8:01amPST. This was a general Amazon outage that affected all of their West Coast data centers. It has been resolved and mail is flowing and all queued mail has been delivered. No email was lost.
We are investigating adding additional redundancy to our expensive redundant Amazon database system to prevent this from ever happening again.
