Looks like both are external then. StatusPage (api.twitterstat.us) is Atlassian hosted, and looks like it's just the API status. status.io (status.twitterstat.us) is another SaaS vendor and is the the main status page for Twitter (as linked off Twitter.com) Why you'd need both/different vendors for each component is beyond me though. Both will allow you to show various product components in one place. Twitterstat.us itself top-level goes nowhere. I wonder if that's deliberate.
