So I was a little paranoid about the Conficker virus. I checked all the updates to Windoze and the AV. Early last week I was doing some more checking around just to be sure and noticed some outbound port 80 traffic from our server. Every once in a while I open a browser from the server to do a quick whois lookup or manually download updates. But none of the IP addresses were for those. So I immediately blocked those IPs and forgot the issue. Today I was trying to do some troubleshooting with one of the companies we get XML feeds from. We hadn't been getting any clicks through them for over a week. Putting the calling string in a browser gave results fine, but now when called through the server. Right after sending a message asking if we had been put on a blacklist on their end, I remembered back to our firewall changes. Sure enough, their IP was one of the ones blocked. Removed the rule and everything works fine.
Sigh. If you'll excuse me, I have to go to the hospital. I think I have a concussion from slapping myself upside the head...
