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.
I have been with Plusnet for around 4 years, initially on the monthly 10GB allowance package (was enough for me then) before upgrading to unlimited for 12.49/month (without the phone line). Generally speaking I think it is a good ISP overall.n top of that, the regulator says Plusnet's 76Mb fibre is the fastest for uploads, offering an average speed of 17.1Mb. They were somewhat unusual in offering similarly fast uploads to their 38Mb customers too, but since June 2015 new 38Mb customers have had to make do with uploads of up to just 2Mb.
