Faster, More Awesome GitHub Pages
Interesting how ALIAS records are becoming a de-facto DNS protocol feature. Despite not having even an RFC draft proposing their existence, GitHub recommends using ALIAS records, and large players (e.g. AWS, Dyn, and DNSSimple IIRC, as well as us) now support adding ALIAS records to a domain.I wonder why ALIAS took hold but DNAME and ANAME records were never widely supported despite actually making it into a few RFCs. Hrmm.(Disclaimer: Namecast (http://www.namecast.net) supports ALIAS records as well, so I have an abnormal interest in what was otherwise a small part of the article.)
