If you're wondering why you can't get at your dynamic DNS domain today, here's why.
Basically all of the noip dynamic DNS service has been taken out by Microsoft, aided by a judge who probably can't spell DNS, let alone have an idea what is actually being seized.
No alert, no discussion, just wander right in and grab your domains out from under you.
