ATT sucking (more than usual) in Davis-ish area?

I've got ATT service on my cellphone. Lately, I've been noticing that my connectivity (particularly north/west of Davis along Holland St, where I work) has been sucking a lot. I mean, I know I'm a troglodyte and I work in a basement, but usually I get pretty good connectivity at my desk. Anyone else in the general area on ATT been noticing cellphone signal problems?
