I Think We've Found the Culprit

I think we've found the culprit of the system instability. It looks like the performance enhancement we put in place last week was preventing Internet Explorer from caching images properly, causing significantly more (like 100x) images to be requested from the server. This was totally weighing down the server and led to much of the instability we have been seeing.

We've pulled out the performance enhancement and we are going to look at it some further to see if we can't get it back in there with Internet Explorer caching properly.

My apologies to everyone who has been having trouble on the site for the last week or so. We should have caught this earlier.
