So status.discord.com redirects to discordstatus.com - so it already is on a different domain. But the domain matters very little unless your DNS infrastructure is offline. However, then you have to assume your status site and domain have to have their own DNS. Unless you're really dedicated, you'll have some SPOF that can take down both (think even different domain registrars).

What most companies need is a solid status page that's hosted in very different infrastructure... that is very static or can scale very fast. Often the do the first... but not the second. If something like discord is down and 10 million daily-active-users all try and check the status page... they'll just DDOS that out of existence as well. Again, if not well built
