This incident has been resolved but we believe it triggered a worsened incident overnight Sun night/Mon morning (US PDT) which has just been resolved. To be confirmed by full RCA, we believe a deluge of large repo uploads tied up individual web servers that handle frontline requests. Each web server is able to recover on its own, and did, but as volume increased all servers were eventually affected, only allowing short windows where requests could get through—rejecting most requests with 504 errors. We'll post a post-mortem when we understand more about what happened and how to prevent it going forward.
