I've never had an outage on my own system that didn't take two seconds to fix because some service just needed restarting.

When you don't have to cater to more than 1 user, there are VASTLY fewer things that can go wrong in a way that takes a long time to fix.

Consider yourself lucky that you've never had a hardware issue.

If you're not prepared to deal with that, use a VPS host. That's what I do.

A curse and a blessing. You can fix it as fast as you want. For github, everyone will stop pushing/merging and you will have to wait for them to fix problems you will never encounter.
