Backlog of feeds that need updating
Incident Report for
The issue has been resolved and we have identified the cause.

This morning we made a smaller change to how timings of feed updates are stored. During the migration a bug happened that caused each feed to have multiple update "threads". This combined with another bug caused feeds never to be marked as "updated" during a crawl. So feeds were never marked as "updated" and thus feeds were being recrawled over and over again, causing the backlog.

We have identified and remedied what we believe caused the backlog to form. We're monitoring the situation and are trying to understand why and how this happened. Expect an update shortly.

We are experiencing a larger-than-normal backlog of feeds that need updating, causing delayed notifications of new posts. We are investigating why this is happening and working on a fix.
