Where I live, all five providers I’ve examined advertise their home broadband plans as unlimited, but four have a limit (mostly called a “fair use policy”) between 3.3 and 3.5 TB, after which they’ll be shaped to 1 Mbps. Suspiciously colludy. (The fifth: “These are unlimited plans for home use only. You can consume unlimited data at high speed. However, [we] may discontinue the data services in case of misuse, fraudulent, unauthorised or commercial use.”)
At 50 Mbps, you can theoretically exhaust this in just over six days. At 1 Gbps, it takes less than eight hours.
Once shaped—a month of 1 Mbps is less than 335 GB.
So in practice all these unlimiteds boil down to less than 4TB/month.
Wish the FCC had listened to us when Comcast first introduced their first very high bandwidth cap in their first market. (Must’ve been more than a decade ago, maybe and a half.) We knew how bad it was in Canada.
