What service do they use, exactly? I think most of us would be interested to hear about a high-bandwidth, low-latency option that isn't cable or DSL. The only things I can think of are satellite and cellular, both of which have huge hosts of problems for regular home use.
Oh your want high bandwidth and low latency? Just like Tesla doesn't have a dealership in my neighborhood, providers aren't available in their area that offers both of those things either.
They use to use pairbonded dial-up, then ISDN. Been on Satellite (high-band down, dial-up up then bi-directional) for the last 10 years or so. They've been thinking of switching to a 4g hotspot recently, which is similar bandwidth and half the latency (and similar cost for their uses).
