I have quite a few domains registered at GoDaddy, and I'm using their nameservers.
Each domain uses 2 nameservers, such as NS10.DOMAINCONTROL.COM. Recently I have encountered a problem where many people emailed in that some of my hosts are inaccessible. After some investigation, I found that all these servers were hosted at the same DOMAINCONTROL.COM server. Some regions in the world failed to resolve my hosts, some managed without any problem.
My question is: is there any recovery from this? What can I do to fix this when this problem happens again? Any tips would be great!
PS. The dns soa started working again (with all propagation) after 4-5 days. In between it was pure hell.
