When using it every day (and especially when using Github Actions), there's something broken or half-broken nearly every day.

Most random errors in Github Actions (e.g. jobs just randomly failing or getting stuck and requiring a manual restart, or just being plain slow) also never show up on the Github Status page. The Github Actions VMs are also so slow that I'm seriously pondering setting up a cheap throw-away laptop at home as runner, that would easily be 10x faster. But then we're at playing IT admin at home :/
