I restarted the server on June 14, and only today (July 1st) realized I didn't start the daemons.
I was actually watching the Feed page daily at that time, and didn't realize that it wasn't being updated.
Maybe get some kind of an external status-checker run a daily check on the server status? Anyone knows a relevant service?
There should be a systemd service for managing the daemons, I'll check tonight what's wrong with it and why it isn't correctly starting daemons on reboot
I think it's relevant to have a status site (likely at status.phorge.it). Uptimerobot sounds like a good option and is used by translatewiki.net.
One thing that's optional to have (likely not possible with Uptimerobot) is a Daemon status checker, as @avivey pointed out when they forgot to start the daemons at some point. For this, a custom status checker that calls a daemon that's not for making edits or changes can be used.
I have a question: Do Herald webhooks rely on Daemons?
