From 2024-05-10 9:40 PT to 10:15 PT, the background queue service was degraded. This was caused by the database used for the task queue had exceeded the capacity.
This issue was mitigated by scaling up the database. We have reviewed the substantial fix options, and now the database usage is significantly below the maximum capacity. We have also reviewed and updated the monitoring for the same situation, and alerting rules are also configured now. We do not anticipate the same issue will happen in the near future.
