When I try to post a comment on this site or Serverfault, I can't because it is just hanging on loads from other sites such as gravatar.com, quantserv, or sstatic.net. This is not happening to me with other GA sites, any I can resolve www.google-analytics.com fine. Other areas that seem to have this issue with me are the formatting edit bar (The thing with Bold button), deleting comments, or tag completion. So it seems to be all the sort of dynamic content on the page.
Same thing happens when I tunnel my connection (Both web and DNS) to a computer on another provider (Comcast Vs Speakeasy), both are geographically in the Boston area though.
random mentioned the browser and I thought he was right. When I did a 'real' refresh with Ctrl-F5 in Firefox 3.5 everything it seemed it started working again, but still the same problem.
I closed the browser and flushed my cache and still having issues. Need to press the stop button for the dynamic content I mentioned to start working. My browser Firefox 3.5 on Linux. I am not having the problem when I visit the site with Chrome using my Windows VM.
Update:
So closing the browser and flushing the cache does fix it, but only for a little while. The problem keeps coming back after browsing the sites for a little while. I tried upgrading my browser to the latest 3.5.x in the repo as well.
firefox -safe-mode
(Got the safe mode pop-up). Good idea though ...
