That feeling when you're cleaning your desk after a 17 day vacation, and decide to rearrange a few things, but it requires you to reroute power, so you just shut down your laptop and flip the power strip off... only to wonder later why your #selfhosted#mastodon server is offline, and then you realize, you also powered off your Mac Mini ESXi host earlier... ...And now we're back up. 🤣
@Stark9837@chuck healthchecks.io will do what you want. you can also self host it somewhere else if you want and set it up to send emails or push notifications when things don't call in with a ping.
There are some edge cases where things might not be caught (and notifications over matrix go silent if my synapse homeserver goes down) but it’s better than nothing.
