Instructions to unsubscribe from this list at the end of the message - --------------------------------------------------------------------- Hi Sims,
Did you make a change to the domain name, or the website contents? If it's a change in the domain name, this has nothing to do with the ISP's policies. When you create a DNS entry, one of the data items you specify is the "lifetime" of that DNS entry. So, if you create a domain name and set its expiry to 1 week, it will be retained for a maximum of 1 week in DNS's worldwide. It's the way that DNS works - the first time you request a domain name, it will query its registered nameserver, then retain that name for up to the period specified in the DNS entry itself.
