New mandatory rules regarding Whois etc. and accurate email notices etc. killed one of my sites... since 1997 on a routine card renewal, wherein it makes no difference the site was paid 30 days in advance there was an email apparently sent to an outdated addy, which I never saw, and resulted in a suspension of my DNS for that site.
Check your stuff, kiddies. This might happen to you.
At present, dealing with the registrar, I have had no love at the moment (12 hours down and nothing hinky, just and old Whois)
ICANN is adamant (per US Federal requirements) for First name and Last Name and Email address (at least that's all they are asking for right now but you know that will not be the end of it... will want your first born, dog and cat, and medical records, too...)
In my case that Whois was from 1997, my renew file made all that happen routine and it slipped between the cracks the address change and email change had occurred. Can happen to anybody. Just watch for it!
And if the email address in your Whois is NOT your current, you, too, might get shafted.
