Mediatemple.net dns server change affects vanity servers

If you use mediatemple.net for dns/hosting and have hard coded dns servers to the ip addresses of ns1.mediatemple.net and ns2.mediatemple.net the IP's have changed. See mediatemple.net support page for correct ips. Mentioning this because sites with them went down if you have hardcoded your own vanity nameservers to those ip addresses Update: Apparently they changed last week but the old servers were still active until yesterday. They had no notification of this to customers.
