I've been having problems only on the FT site. It has been regularly locking up just after the top menu loads. It shows as done from after the "my flyertalk Have it your way..." button. When this happens it also seems that some of the menu items overlap each other - instead of a drop-down menu on forums, the Forum Home shows up over the existing Forum button.

I can refresh a time or two and the page will load directly. I'm afraid that there is more of a problem than just SEARCH.
