Incident with Issues and Pull Requests Search
Final update
On February 23, 2026, between 21:01 UTC and 21:30 UTC the Search service experienced degraded performance, resulting in an average of 3.5% of search requests for Issues and Pull Requests being rejected. During this period, updates to Issues and Pull Requests may not have been immediately reflected in search results. During a routine migration, we observed a spike in internal traffic due to a configuration change in our search index. We were alerted to the increase in traffic as well as the increase in error rates and rolled back to the previous stable index. We are working to enable more controlled traffic shifting when promoting a new index to allow us to detect potential limitations earlier and ensure these operations succeed in a more controlled manner.
