After having them in other towns, because no other options were available. I went and kept them...and then the price went up...and up...and up...and it doesn't stop. They are the worst and need to be shut down.
While not available in all areas, fairpoint "FAST" internet is very good. This is not to be confused with their DSL service (available in more areas but slower). I have the top tier service and it works great. I've had it for as long as fairpoint has been in NH (actually even longer since it was originally installed by Verizon before they left the state).
Another review mentions speeds vary based on weather. I've never seen any evidence of that.
In the years I've had service, it has failed twice. In both cases, they had service techs here within a day and addressed the issue. (One failed power supply for the indoor router/access point, one failed battery in the primary fibre interface).
