True. how about https://ycombinator-status.com or https://status.ycombinator.com. They can drop that link on their official ycombinator.com site just so it is easy to tell that it is legit when they are not down. They can maintain the status for all of their official sites there. Well, with the exception of ycombinator-status.com of course. I guess they can post that status on some-sketchy-domain/status-right-now - LOL!

Maybe ycombinator does have an official status page somewhere, but it is not easy to find if that is the case.
