Viasat service has been amazing. I have been happy because 90% of the time the speed has been over 100mbps down. The only time it's been bad is heavy storms. We burned over 700gb the first month.
This opening post has been very enlightening and helps me understand why I got the phone call I did today. Sorry I can't say more but I wouldn't be a bit surprised if folks in the HD beams start seeing their speeds slowed quite a bit after they go over their priority data. The system simply can't handle this type of traffic per customer....that is unless they want to close the beam to new sales.
