: GitHub PR diffs delayed; partial outage resolved
GitHub experienced a partial impairment in commit processing that caused pull request diffs to appear stale for several minutes, slowing PR reviews for some users. Impact began at when the Pull Requests component was flagged as having delays and the team began investigating while scaling up resources. The situation persisted as investigators worked to restore normal update times. notes indicated the diffs began improving toward normal thresholds, and by the PR diff updates were back to typical speed, with the component returning to normal.
In short, users experienced slower PR diff updates during this window, impacting review workflows briefly before full operation was restored.
