Update: After nothing happened, I rewrote the last commit and force pushed to trigger an update. That seemed to do the trick. I have no inside knowledge, but from the outside it looks like whatever outage they had broke the propagation of commit data from the git repo to to their MySQL database. Maybe they use webhooks for their internal systems as well? That would explain why they first saw issues with webhooks, and later issues with pull requests that might depend on them. It also looks like after they fixed the issue, they didn't replay the failed notifications. That's why I saw stale data even after they apparently fixed the issue. Then my push to the repo seemed to trigger an update, and now it's back in sync. I'm curious to hear what really happened, but I doubt this incident is important enough to anyone to warrant a detailed blog post.
