Actually, it's not that simple (I'll stress again that this is *my*
particular need, but not one that is particularly uncommon)

My monitoring service is me, with either my phone or a laptop.

I need to be able to connect from a variety of countries, and a (for my
purposes) essentially random series of ISPs and routing networks.

I understand completely that this isn't the same as /your/ need - you are
obviously providing a specific service to a very geographically limited set
of known users. Although I'd be wary, once one of them attempts DR. 'Tis
amazing what comes out of the woodwork when that happens... I've had to do
it for real, courtesy of the PIRA.
