What lies!
It's 8:03pm EDT (5:03pm PDT). I still cannot access most of the services I have forwarded on my home router using the no-ip domain. Microsoft most certainly has NOT fixed the problem!
I received an e-mail from no-ip telling me that I should setup a new host using new primary domains that they created after this fiasco began... but the no-ip.com website is not responding (presumably because so many people are trying to setup new host names).
Microsoft claims that 93% of no-ip hosts were participating in malware. I find this to be completely unbelievable.
I switched to a different DDNS provider, and I'm sure many other people will too. No-IP should sue Microsoft.
