قطعی Asana در ۹ شهریور

Asana full outage for some users (2 hours, 25% outage)

1. حل شد · ۲۱:۲۹

   We’ve been working to add a caching layer to our update pipeline, tuning it carefully and rolling it out gradually. On Wednesday, August 26 we enabled it for most use cases, and it initially performed well. On Monday, August 31, a combination of unrelated infrastructure changes and peak traffic pushed the cache past its scaling limits. Once that threshold was crossed, the cache became unusable, and many pods serving read traffic for the Asana application could no longer serve it. We mitigated the incident by reverting the system to use the previous, non-cached code path. The revert was successful, but recovery took longer than we would expect for this class of issue. A fuller analysis is underway. We will follow up with root causes, action items, and improvements, including why recovery took as long as it did. We were fully down for about 25% of our users, for 2 hours, 15 minutes.
