Yikes! That would have been the wrong thing to change. You're paying Dotster to provide your DNS service. Thus, you want to keep your DNS servers as is.

The primary purpose of DNS service is to field questions such as “what's the IP address for peterkupfer.com?”. The correct answer used to be “129.22.134.50” and now it's “129.22.144.15”. Look through your Dotster DNS configuration for occurrences the old address and change it to the new. Within a day or two, it'll be updated.
