Back in December 2008, Google was finishing the process of deploying the new Google Apps DNS servers - a set of 4, to replace the old set of 3 . Around that time, Blogger Support had (unofficially) stated that they would inform us when the old 3 servers had been officially retired, so bloggers everywhere who used the Custom Domain Asymmetrical DNS Configuration would know, definitively, when it was essential to update their DNS setup. It's now 9 months later, and we have still gotten no official word. In the mean time, almost weekly, we see problem reports with attempted use of the old 3 servers (all long offline) being the center of the problem. Enough. In my opinion, all bloggers using the old 3 servers, for their domain DNS, need to update their DNS setups. You need to have your domain using the 4 new Google Apps DNS servers . For the record, I will now state this. Anybody with a custom domain using a DNS setup of mydomain.com. 3600 IN A 18.104.22.168 mydomain.com.
