With the addition of the IDN string қаз (Kazakhstan), the number of IDN and country code Top Level Domains has reached 280. The total number of TLDs, including Latin and non-Latin (IDN) country codes, generic and special purpose, is now 313. The number 313, of course, has the distinction of being a palindromic number, which is certainly cause for celebration.
