So I got up this morning and thought: I know, today would be a good day to set up my own Activity Pub host.
So I did that, and then I found out Cloudflare is yoyo-ing destruction across the internet, and now I have no idea at all whether the slightly alarming failures rates are me not having a clue or somebody else's problem.
I mean - some things are working some of the time so it's probably not me, maybe?
