Yet few are managing to wring out the number they were promised "up to" during higher traffic times. My 60Mbps service universally drops precipitously in the evenings but during the lower usage times, it can be faster that 60Mbps. As an individual, I'm obviously set up for higher speed but if the network of combined individuals is set up for half or less than the sum of their "up tos" then that's what it really comes down to.You know as well as I do that is garbage. No ISP is going to sell 100 Mbps service and intentionally scale it back to 70. Comcast, Charter, Cox, Altice, Verizon, AT&T even HughesNet and others all over provision by up to 20%. In the GUI on some cable modems you can see the exact provisions set by the bin file. There is enough evidence scattered around the internet to prove the majority of providers over provision their tiers.
Last night I ran a speed test with no significant traffic in my home (just my weather station, VOIP phone and my thermostat) and the numbers were in the low 20s. Somewhere along the path between myself and the Internet, I'm alotted perhaps one third of my "up-to" speed in the aggregate of my neighborhood so that's what I'm really provisioned for.
It doesn't matter if you subscribe to a car can do 150mph if you're stuck in heavy traffic.
