As some of you know, my regular game IP, bg.servegame etc, would not work yesterday. Fortunately, my numerical IP was still working and I was able to host.
It appears that my bg. servegame account was cancelled without prior notice. I was able to create a new account with all the same details as before. I have sent Dyndns an email asking how much it would l cost to upgrade my account so that this does happen again.
Since this has happened to me it may happen to those of you who are registered with Dyndns.
I'll post back when I get a reply to my email.
