Massive Stability Issues on Gitlab.com

Summary

I'm not sure what the exact bug is, or if this is even the right forum to report it, but over the past 1-2 months, we've noticed severe degradation in responsiveness and reliability of gitlab.com. Problems we've encountered:

• Private runners losing communication and requiring a restart/re-registration
• Inability to push/pull from our repositories due to rejected credentials. This one happened again this morning, with ssh -T git@gitlab.com responding with ssh_exchange_identification: Connection closed by remote host
• Merge requests not showing latest commits
• Pipelines lagging by minutes after a commit before they even appear in the UI
• Merge Request view unable to communicate with Pipelines service
• Pipeline jobs completing, but Pipeline service not recognizing a job has completed for several minutes, preventing downstream phases from starting
• Pipelines completing but UI lagging by several minutes before marking the pipeline as complete instead of "In Progress"
• Periodic inability to connect to gitlab.com from web browser

I'm not sure what happened. Using gitlab.com used to be a great experience. Now, it's getting frustrating to the point that we're considering alternatives; not only for our repositories hosted on the SaaS offering, but also for our enterprise licenses.
