Wanted to provide more clarity about this.
Yesterday, we had a regression in merge queue behavior where, in some cases, squash or rebase commits were generated from the wrong base state, making earlier changes appear reverted in branch history. 2,804 pull requests out of over 4M merged on April 23 (roughly 0.07%) were affected. We fixed the issue, we've contacted every impacted customer, and we're expanding our automated test coverage for merge queue operations. The team will be updating the status page with RCA details as well.

This GitHub incident is insane. Merge queue commits have been reverting previously merged commits at random. This not only breaks the mental contract teams have with Git in general, but is subtle enough to be really hard to unravel after the fact. githubstatus.com/incidents/zsg1…
