I'd really like to find a website that displays the percent uptime for each of the lemmy instances in the Fediverse. Does one already exist? If one doesn't yet exist, I'm considering making one. In that case, does anyone have any recommended very-simple linux tools for this? I've used `mon` before, but I don't think it records previous failures and calculates uptime. If I do make it myself, it needs to run on Linux and I want something extremely lightweight (ie not nagios, checkmk, etc)
