It's worth noting that cloudflare's status page is hosted there. Pretty good proof that it works
And I got a 504 error (served by CloudFront) on that status page earlier. The error message suggested there may have been a great increase in traffic that caused it.
Maybe that's precisely what Cloudflare did and now their status page is down because it's receiving an unusual amount of traffic that the VPS can't handle.
They should have had Cloudflare on it.
Even the Cloudflare status page, hosted by Atlassian Statuspage, is suffering. Probably due to the traffic crush.
