I've been having a lot of trouble viewing certain websites - Gawker Media, DeviantArt, etc. - and through further investigation they all appear to be using a CDN called Cotendo. On my machine, and only this one, connections reset themselves midway through the download most of the time. This is not browser-specific; even wget (Cygwin) is unable to download anything without retrying a few times. This happens inside virtual machines as well.
Unfortunately, I'm pretty stumped on why this is happening. My hosts file is empty (except for a couple LAN-specific things) and I've checked a few different DNS servers, but I can't really think of anything else to try. Anyone have any ideas?
