I'm barely able to connect to Microsoft at times. I just checked the firewall logs. There's a massive amount of connection attempts coming from 207.46.249.61 (wu-ori.microsoft.com). However, it's important to note that this IP is being spoofed by the MSBlast worm. It's attempting to connect to a random port between 1000 and 2000 every 2 seconds. The source port on the attempts is port 80, otherwise known as HTTP. The way this DDoS works is it attempts to connect to the port. However, because of the spoofed IP and port, the response to the connect attempt is sent to Windows Update on port 80. That means that all of you who don't have a firewall are contributing to this even if you aren't infected. If you're unprotected, please do everyone a favor and get a firewall.
