Background in T293504: non-wikimedia.org domain names for status page; tldr:

• Statuspage needs to use a custom domain name for several reasons
• Atlassian supports custom domains via you setting a CNAME record
• Original plan was to use a HTTP redirector provided by our registrar, but, our registrar doesn't support mixing HTTP redirection with "real" DNS zones

Currently we have the CNAME record configured for www. on the zone. We need some URL redirection service on A/AAAA at the apex of the zone. I was thinking that this might be a fine use case for ncredir? Although one thing I did notice is that the existing acme-chief domains seem to all use a dns-01 challenge, which won't work here -- wikimediastatus.net's NS isn't on our infra and we don't want it to be.
