Google Fiber Speed: By the numbers. The average Internet speed in the U.S. is 7.4 megabits per second (Mbps), according to a âState of the Internet Reportâ released by Akamai Technologies. It seems that the U.S. has some catching up to do in this department.
However, AT&T has a cap of 250 GB per month, and despite what the salesman told me over the phone, Iâm pretty sure that I do need a 24 Mbps connection today to satisfy my family members. Still, on the eve of the Google Fiber announcement Iâm tempted to switch over to AT&T while I wait for the build out.
