Processing delays for repos with 5K+ source files

We've seen a spike in build times for large repos (5K+ source files). Right now, only nine (9) repos seem to be affected. We have implemented a fix and are monitoring as build times return to normal for these repos. The root cause of this spike is elevated jobs (and therefore dequeue times) in queues dedicated to large repos which appears to have been triggered by two (2) repos sending an unusually high number of uploads over the past 1-3 hr period. We have increased resources to these queues to accelerate processing but may need to pause the above repos if uploads continue at the same level. If you think your repo was affected you can reach out to us at We will reach out to the owners of the repos with elevated jobs.

Issue affecting coverage details for some repos (Fix being implemented)

Internal testing today revealed an issue with some repos, in which coverage calculations and data for particular builds show obviously large, incorrect drops in coverage and/or missing coverage data. We have identified the root cause of the issue and a fix is being implemented. If you are wondering whether you are affected by this issue, know that, once we've resolved the issue, we will re-run as many affected builds as we can identify, but feel free to check in at and we will verify and make sure your build are recalculated.

Drop in coverage for some parallel pull_request builds

After a recent release, we have received reports of `pull_request` builds that have suddenly dropped in coverage with no change in CI setup. Specifically, these builds have had several parallel jobs and now, suddenly, have only one build. We are aware of the issue, have identified the root cause, and are working on a fix. We will update this incident when status changes.
