Might want to check your git logs if you are using the Merge Queue feature. This afternoon, we found that Merge Queue was silently reverting changesets in the merge queue. Acknowledged by GitHub, but could be a very hard problem to debug if you aren't looking for it.by matthewbauer

The window to audit is 2026-04-23 16:05 to 20:43 UTC, about 4h 38m, and 'merged incorrectly' is unpacked in exactly no detail on the status page. Practical check is to compare the tree of each merge commit in that window against the tree of the rebased-and-tested commit that the queue ran CI on. GitHub Enterprise Cloud with Data Residency is still affected as of the latest status update, so DR customers shouldn't clear new queue merges yet. Would be kinda useful if GitHub published the specific failure mode, because content-drift and parent-linkage and dropped-changes all need different audit scripts.by cwkcw

4 people spent hours putting our repo back together at my company after this. GH has been unreliable and now they are breaking the core tenant of what I expect from this service.by MarkMarine

Tip: identify PRs with this problem by looking for discrepancies between the metadata (files/lines affected) for PRs via GitHub API and associated commits in the time window.This was a pain to clean up!

This has caused a morning of fun for our team, how do you break one of the most fundamental bits of your system? Time to look at alternatives...by EdwardDiego

Self-hosting has been wonders. I thought I needed the social part of GH (i still kind of do, I like seeing what people are working on or liking) but overall its the same experience.by ramon156

How long will users put up with this before they finally leave? Microslop is inventing new failure modes on a weekly basis.by classified
