The site seems to be freezing a lot

[Joebob]

Just sayin'.

Is this happening on particular pages, or is it site-wide?

It happened to me yesterday in the afternoon (Boston)... it affected the entire site. Finally I just left. Everything seems pretty good today.

It happens here (I'm in Mpls/St. Paul) frequently in the mid-afternoon, most recently yesterday (8/22/12). By frequently, I mean a couple of times a week on average. Site-wide. I've noted it lasting for over an hour at one point, but I don't always check back until much later if it's acting up.
