A hospital using up "emergency mode" GSM capacity doesn't make much

This was just a guess on my part because the congestion
in this suburban area lasted well into the evening.

Could be lots of things. Maybe it was really the hospital, but then simply the people in the waiting area calling all over the place. Or maybe some completely unrelated problem with the cell network in your area.

When it gets
really bad the random access channel gets clogged and all mobile-
intiated communication, including SMS, is dead in the water.

I never had a problem sending or receiving SMS other than
the long delays. The people on the other end were near
Aldgate on the edge of central London so even there, SMS
was still functioning.

Follow the money... At several hundreds of your favorite currency unit per megabyte, I'm not surprised they manage to keep this service running.

Here in the Netherlands we had free airtime for a few hours at the beginning of the new year several times, and it was interesting to see what this did to the networks.
