Throttling is the intentional slowing or speeding up of an internet service by the internet service provider. Based on this definition, Yes, Viasat does throttle speed to slow down service when a customer has used more than their unlimited data plan has accounted for and there is a higher than normal capacity usage in their service at the same time. The way it works is if a customer is on a plan and they haven’t passed their data cap then their service should not be throttled, but if another customer is on a plan and they have passed their data cap, they possibly will have their service throttled. The priority of good service goes to the customer who hasn’t reached their data cap yet or for the customer who has used the least of their plan. There isn't a set number for customers who can be using the service before a customer's service is throttled because it depends on the data being sent over the satellite dishes. When too much data is being sent between the dishes then it can’t take on anymore so it needs to decrease the data being used by some customers to make sure more can use the service. Throttling is needed for the internet service provider so the same customers don’t occupy the service and other customers can’t get on to use the service. This is used to balance it out so everyone has the same chance of getting good service. To not get in the position of being throttled a customer should use little of their service so that they are always at the top of the priority list.
