Zerigo have just removed their free plan. As a result I need to switch out my DNS handling. The problem is that the site is live, so I need to minimize any downtime.
Currently Zerigo handles both the naked domain and the www
subdomain. So far as I can see I need to do the following:
- Switch nameservers back to my domain registra's
- Add a CNAME for
www
, pointing toexample.herokuapp.com
- Add an A record, pointing to wwwizer's IP address (
174.129.25.170
), with Wwwizer handling redirection of the naked domain.
But how can I do this without downtime?
