I wondered the same thing at the time it had to have been ungodly expensive unless it was a stolen device. I can’t remember for sure if it was intelsat or one of the other companies that was around at the time but it was a sat connection. I was also running that webserver on a really bad dsl line. I lived right next door to the phone company CO but was at the end of the line. I had to go with an independent isp because the phone company said it was too far and wouldn’t work. It did work but was super unreliable.
I used to really like running it. I had quite a lot of aggregated content on that site.
