We need at least one custom domain registered solely for the status page.
* An external provider is hosting the site, so we can't use a subdomain of wikimedia.org
* We don't want to use a subdomain of wikimedia.org anyway, because we want the status page to be totally dependent of our infrastructure (which includes DNS)
* In order to use custom CSS/HTML/JS, Atlassian requires you to use a custom domain, rather than a subdomain of statuspage.io. We need custom CSS/HTML/JS both for styling, and also to do i18n/l18n.
I recommend we register both wikimediastatus.org and also wikipediastatus.org (a simple redirect to the former). I could also be talked into registering .net variations of both of those domains.
We'll also need simple static DNS hosting for both of those, although I expect that to be trivially provided by our registrar.
