Fortunately, I've got my own domain name registered and coupled to my no-ip account, but my free no-ip domain name is definitely not working.
I won't go to town (yet) on Microsoft for doing what they did as I don't know all of the details. However, their continued incompetence with regard to blocking legitimate users' domain names beggars belief and they need to pull their collective finger out and fix it.
Also, although in a way it makes sense that Microsoft be the ones to do this "filtering", it seems odd for a non-government agency to be handed what is effectively seized assets from another company. In no other industry that I can think of would this happen.
