The following notice is to merchants who manage their own DNS.
In preparation for possible site moves tonight due to the denial of service attacks. Please update the TTL on your DNS record to be as low as possible, ie usually 300. If we manage your DNS, do not worry about this, its already done.
If you don’t know if we manage your DNS or not, do a whois lookup http://who.godaddy.com/ on your domain name and look at the dns records, if they are setup to ns.rackspace.com and ns2.rackspace.com then we are managing your DNS and you don’t need to do anything. If not, then you are managing it yourself and need to make the change. It you don’t know what DNS or TTL is then we are probably managing it for you.
