Question - if this is really to be the ultimate status page - a service wouldn't want to use their own DNS - correct? They'll want to use [domain].statuspage.io - right?
Perhaps. Or have multiple domains and DNS providers and point both status subdomains to statuspage. (We created status.phaxio.com and status.phaxio.co after the whole Zerigo fiasco last year. co is on zerigo, com is on Route53 )
I like that - dropping the "m" in .com would retain a sense of ownership of the url.
