As announced last week, ns1.webfaction.com will point to 188.8.131.52 (instead of 184.108.40.206 currently) and ns3.webfaction.com will point to 220.127.116.11 (instead of 18.104.22.168 currently) starting tomorrow.
If you own any domains and use our DNS servers then you may have given the previous IP addresses to your domain registrar. If that is the case then we recommend that you update the IP addresses in your registrar’s control panel as soon as possible (you don’t have to wait until tomorrow) . Since we are changing the IP addresses of just two of our four DNS server there is no danger of your website or emails being inaccessible while you make the change.
Some registrars only ask for the DNS servers names not their IP addresses. If that’s the case with your registrar then you don’t need to do anything.
