We are investigating reports of degraded performance for Pull Requests
- investigating Oct 15, 2026, 12:06 PM UTC
We are investigating reports of pull requests lists not showing accurate count or state.
- investigating Oct 15, 2026, 12:49 PM UTC
We've identified the issue causing stale results for pull requests lists, and are working through mitigations.
- investigating Oct 15, 2026, 01:32 PM UTC
We've identified a capacity issue that is causing pull requests lists to remain stale. We're working on adding capacity so that new pull requests will correctly show in pull request lists.
- investigating Oct 15, 2026, 02:37 PM UTC
We've deployed a change that unblocks our ability to increase capacity, and are adding that capacity now. Once that capacity is added, we expect new pull requests and pull request state changes to start to be reflected in pull requests lists.

We're currently reindexing data into our new infrastructure, which is expected to complete within 2 hours. After that, fresh data should appear in pull requests lists again (partial mitigation). In parallel, we're executing a full reindex that will include data from the ~20 hour incident window (...
- investigating Oct 15, 2026, 04:51 PM UTC
The reindexing process is ongoing, and we expect partial mitigation in 1 hour, when fresh data will appear in pull requests lists. Full mitigation is estimated to complete in ~5 hours, when pull requests lists will include changes from the ~20 hour incident window.

The reindexing process is ongoing, and we expect partial mitigation in 1 hour, when fresh data will appear in pull requests lists. Full mitigation is estimated to complete in ~5 hours, when all stale or missing data will be up to date.
- investigating Oct 15, 2026, 06:34 PM UTC
Partial mitigation is complete after cutting over to our new infrastructure, so newly created and updated pull requests should now be reflected in pull requests lists. Full mitigation is estimated to complete in ~4 hours.

The complete reconciliation effort for all pull request data is expected to complete within 8 hours (by 2026-10-16 04:00 UTC), but self-healing mechanisms will restore most customer-impacting experiences naturally, before the repair effort completes. In the meantime, any newly created or updated...
