Quoting Dynamoo's Blog:
The nameservers for the following dynamic DNS domains belonging to no-ip.com may have been seized by Microsoft as the namesevers are pointing to NS7.MICROSOFTINTERNETSAFETY.NET and NS8.MICROSOFTINTERNETSAFETY.NET
This seems to have had the effect of taking down any sites using these dynamic DNS services. This will probably impact a lot of things like webcams, home security systems, personal VPNs any anything else that uses these domains.
