- postmortem Apr 09, 2026, 11:36 PM UTC
The Expo push notification service suffered from partial unavailability due to an outage of one of our cache servers. Specifically, we deployed a change that optimized our cache entries to be more compact to improve the performance and efficiency of our caches. However, the cache could not handle the load from evicting the old entries. Clearing the cache solved the problem.
