[UPDATE: Dot.Tk domain parking is available again]
Dot.Tk domains are having some intermittent problems lately. I think the problem is with their Domain Name Sever (DNS). Please note that the problem is NOT with us or our domain parking system.
I don't think much can be done about it except removing the parked domain. If you've parked a dot.tk domain and want to remove it please send me a clear message using the Feedback form.
