## Timeline of updates

- **resolved** 2024-04-10 07:30 UTC: The maintenance is now finished. Our intention was to perform a minor upgrade to Aurora PostgreSQL 14.10 and upgrade the AWS instance type we use for our main database cluster. The version upgrade went as expected, but we ran into unexpected errors when trying to perform a failover to the new instance type. During the maintenance period there were three periods of elevated error rates: \* ~5:45 UTC - there were about 4 minutes of elevated error rates while the upgrade was being performed. This was estimated to be about 30 seconds during our trial run, but ended up being much longer for the real upgrade. \* ~6:00 UTC - there were about 2 minutes of elevated error rates from an unrelated database performance issue where where writes are blocked on IO:XactSync. We are working with AWS to find the root cause of this and believe it is unrelated to the maintenance. \* ~7:25 - ~7:50 UTC - once the database was stable we ended up in a situation where a pgbouncer cluster for read queries was still pointing to an incorrect instance. This resulted in a more severe outage where about 30% of posted receipts were failing and a 1.5% error rate across all endpoints. All purchases that failed during the outage have been captured and are being replayed.
