Unfortunately, events like this are one of the reasons I never was able to go all in on Gitlab. When I first started trying it out the performance was not great (it is pretty good these days though) and they just seemed to have more of these smallish events. I realize Github also has problems but it feels like they are much less frequent. I don't have any data to back that up though.
Either way, went self hosted recently so now I only worry about my server haha.
