Unable to Add a new domain "Zone failed validation test."

[phelenius]

Hello I just tried adding my new domain to HE DNS and got the following error.

Zone failed validation test. (141592653589793238462643383279502884197169399375105820974944592.sexy)

Any clue what validation test this is failing?

Any clue what validation test this is failing?

I have four guesses for what might cause software to reject that as an invalid domain:

• Checking TLD against an outdated list of all valid TLDs
• Using the first character to distinguish between IP address and domain name.
• Checking the length of the domain name against the maximum length of a label (63) instead of against the maximum length of a domain name (255).
• Off-by-one error in checking label length against maximum permitted length.

Also, why does the value returned have the first 63 digits of the fractional part of pi?
