We had a partial outage (some requests could not access the platform at all) and some builds were stuck in pending for 30 mins.
We manually detected this issue before our automated check (every 10 minutes) alerted us
We had a parallel issue with Firebase logging and the combination of a number of small issues as a result caused some pods to become unresponsive.
We reverted our last push to production to test if this was code related. Once the revert triggered services to restart, the issue was then resolved.
