I had posted a while ago that there was going to be yet another maintenance issue coming up.
As you recall, we did a massive switch to a new server last October. That went well.
This time we had to point the domain resolution from the old server IP address to the new server IP address. The traffic to the old IP address was “proxied” to the new. Now, when someone seeks the IP address for the blog, it gets the IP address of the new server, thus removing an intermediary step.
