Cox slows Internet speeds in entire neighborhoods to punish any heavy users

In the case we will describe in this article, a gigabit customer who was paying $50 extra per month for unlimited data was flagged by Cox because he was using 8TB to 12TB a month.

Cox responded by lowering the upload speeds on the gigabit-download plan from 35Mbps to 10Mbps for the customer's whole neighborhood. Cox confirmed to Ars that it has imposed neighborhood-wide slowdowns in multiple neighborhoods in cases like this one but didn't say how many excessive users are enough to trigger a speed decrease.
