I am running a tracert right now to check if its a node in my area or yours, but quite frankly, I am getting garbage performance from your domain (or rather the IP you resolve to). I have not been able to get over 1% on the updater except when I downloaded the patch manually starting and stopping the download over the course of hours. In the end, the updater just wrote over the patch20120904181945.dat file I had gone through all that trouble to download and I am back at 0%.

Cutting out the unimportant bits traveling through Comcast, across the US, and into Washington State, it ends with this before it starts timing out.

Now I don't know if you have the server set not to reply to pings or tracert style packets (and if you know how tracert works it is such a hack), but its looking pretty bad here and for once it doesn't seem to be my ISP. Your site is taking upwards of 10 seconds to load a page when a page loads at all. Are you under a DDoS attack or something? Is anyone else having these issues?
