I've had good results with (Verizon Wireless +
Blackberry) in the Washington DC area. A secondary monitoring server
outside the network will send a message if the network problem is
serious enough to break the path from within the network to

I also have a network monitoring system that's smart enough to track
dependencies so it doesn't page me about the http service being down
if it has already paged me because it can't ping the router that the
host sits behind. As a result, I very rarely get a notification flood.
It also keeps notifying until I ack it so if the first message doesn't
go through, the second does.
