If you've got doubts about the distance, have a look at this network. The
long haul links use Tsunami equipment. There's all sorts of stats and
whatnot on the site as well, correlated with weather data, etc.

The main site is:

The long-haul links go up to 45mb/s, and while I can't quite find it, I
believe there may be a few 155mb/s links.
