Last month when we upgraded our core routers in Morton we switched our balancing from MPPP to CEF. I'm not sure the CEF is working right as it's breaking or slowing some access to certain pages. We will be working to switch back to MPPP over the next few days.
The site that is the most displays issue with this is seattletimes.com (http://seattletimes.nwsource.com/html/home/).
