I feel I have to add a few explanations to the above message, so no one thinks I'm an idiot.

There's a part of the internet which is ancient and creaky and might surprise you with its primitiveness. Technical fans of the internet will tell you it's a feature and not a bug and shows the genius of the internet. Whatever.

When you register a new domain, the information has to get propagated through the network before any of the domain servers know where to find it. The IP addresses of servers have to be registered against the name, and the info propagates through the net in a process somewhere between a bucket brigade and a tree. It can take over 24 hours and sometimes up to 72 hours to get into all the nooks and crannies of the 'net. Meanwhile, users of the internet will only see the new domains after the DNS servers that they use (or their service provider provides) receive the necessary info, whenever that is. In other words, not everyone gets access at the same time.

The same process happens when an update drops a domain. That has to propagate as well. In my response above, you can see that I was still seeing the domain after others weren't. That's because the domain server I have my router pointed to still had the old info cached. Meanwhile, others were losing access to it as their local DNS servers updated.

I'm very sorry that my response above made it sound like I was denying there was a problem. I had no way of knowing what was going on, unless I had thought to check the registration record, which I hadn't. Mea culpa.
