I have no idea what it is, but it isn't anything I requested data from, and ft using chrome just sits there and hangs waiting for it to never finish loading now.
If anybody else is interested, you can opt out here:

Here's another one, pixel.quantserve.com, opt out here:
http://www.quantcast.com/how-we-do-i...hoice/opt-out/ (even that doesn't seem to stop pixel.quantserve.net from loading/hanging).
And after all that, now it sits there waiting for images.ibsrv.net and that just hangs. the page is fully loaded with all images, so what is it that one doing?
I guess it must be your advertising tracking cookies, but I have paid to opt out of the ads, so why is it still attempting to load tracking cookies from those sites for me? Especially annoying when they don't work and/or they are very slow.
firefox didn't have the issue, so it might be chrome-related. You support and test with chrome, right? FWIW I'm running the current production version of chrome on a mac with the current OS version and all updates applied.
