A lot of Fediverse software has a HEALTH-CHECK URL.
But not all Fediverse does.
It would be better if ALL Fediverse software had a HEALTH-CHECK URL.
...
A HEALTH-CHECK URL is a special URL that tell others if the system is running properly.
It would return "200 OK" if everything is fine. And return "500 Internal Server Error" if there is a problem
...
A HEALTH-CHECK URL is important to those who actual run and administrate Fediverse servers
A HEALTH-CHECK URL would, for example, make sure:
• the web-server is up,
• the database connection is fine,
• maybe query one or more important tables to make sure that still works,
• make sure any 3rd party APIs are working,
• etc.
If any of those things has a problem, then it would return "500 Internal Server Error".
Else (if everything was fine then) it would return "200 OK".
If you have a fediverse account, you can quote this note from your own instance. Search https://mastodon.social/users/reiver/statuses/114375970714424838 on your instance and quote it. (Note that quoting is not supported in Mastodon.)
