Default SMS Network problems?

I'm in Baltimore. The last 3 days in the Baltimore - York, PA area I've had SMS issues where texts don't send. They hang on an indefinate sending status then fail.

It's intermittant. I didn't change the ROM or make any other updates.

I'm wondering if this is a known network problem or not so I know if I need to fix something or just wait it out.

T Mobile customer service said the network is fine, but who knows how accurate that is?
