The problem came from Context Web, which runs my rotating ad scripts for this site. Here is their announcement page about it. The problem seems to be fixed for the moment now though. https://getsatisfaction.com/pulsepoint/ ... com-17mzh0

I understand many of our publishers are experiencing problems with their pages due to slow loading from tag.contextweb.com and regret the inconvenience. To shed some light on the issues:
1. Over the past several days we have had a number of challenges caused by our datacenter getting overwhelmed with bursts of too much traffic. These incidents have caused sporadic outages across our entire publisher network.
Our engineering team is hard at work attempting to address these issues - and we will be posting regular updates in this forum over the next few hours and days to keep everyone up to date.
To address this challenge, our engineering team has developed modifications to force our tags to load asynchronously. This is a substantial change, for which we are running a closed-beta. At this time we are opening up this beta to publishers reporting consistent page load issues. We believe it will speed up page load-time for many publishers affected by this separate issue. If you would like to participate in the beta (which requires small changes to your tags) and have not yet reached out, please email firstname.lastname@example.org
with a subject line of "TAG BETA:".
Once again we regret any problems your users are experiencing, and thank you for your patience as our team works to address them. We will update this thread at least once a day to keep you informed of our progress.
