Even with the influx of users due to this I was able to not only setup a repo, but push all code up, and deploy via GitLab CI all within minutes... Speed is very good. I don't notice a difference between it and GitHub.
> Also, I don't think GitLab has had a long downtime recently.
That mostly depends on whether you're using CI/CD I'd think, that's had some day-long outages/problems lately. Of course, GitHub doesn't even have it's own CI/CD, and GitLab's is amazingly flexible, so it's still the better product. But it'd be nice if it were more stable.
(Note: all this is on GitLab.com. If you self-host, it's presumably much better.)
I don't encounter all of them myself - it depends on what I'm working on and perhaps also the timezone. That said, April 26th was the most recent occurrence for me where I was very happy I wasn't in the middle of a production deployment that I would have had to roll back.

(I am using the free tier though, so this is more informative than that I'm complaining.)
