The root cause was a change we released to the API this morning that began using a database index incorrectly. This caused a slow drain of database I/O burst quota, until it finally reached zero at 13:10 PST (20:10 UTC). There was an increase in request times starting after the deployment but our alert threshold was not sensitive enough to trigger. We are now in the process of tuning alarms and setting up additional ones to be able to detect these conditions early. We are also going to increase our base I/O throughput of our database and look into performance tests to catch issues like this before they reach production.
