You'd be surprised how many sites reject my domain, 3e.org. Sometimes it's because it begins with a number, sometimes it's because it's too short.

  I've had Gogo's inflight wifi not let me sign up because my email account at gmail started with a number.

  To be fair, an old RFC referenced by an RFC that is referenced by the current thing specifies that a segment of a domain name can't start with a number. Obviously, that isn't true in the real world.

    So, TLDs are selling (technically) invalid domains?
    • LukeShu 11y ago
      And every major implementation supports them. Well, I trudged through the RFCs in ~2010, so it's possible that it's been updated since then.

  Same issue with our hi.fi. Facebook's JavaScript SDK wouldn't write cookies to it, instead rejecting it as too short and invalid. Had to open a ticket and the oversight was corrected, with lots of embarrassment and apologizing.
