FYI: According to Akamai, South Korea is well ahead of the pack when it comes to fast internet. With an average connection speed of 26.3 Mbps, 10 more than the U.S., no country even comes close. The UK has even less to shout about than the States, with a paltry 14.9 Mbps. For an advanced country with a small geographical area to cover, you would be excused for expecting to see the island nation significantly higher up in the rankings.

Here's a table of mean internet speeds that also shows percentage of connections above 4Mbps, 10Mbps, 15Mbps. Data from same source (Akamai), albeit three quarters older (Q4 2015 vs. Q3 2016). It provides a more complete picture, though if you compare means at the two time points you can see the picture is rapidly changing.

The UK may have a lower mean speed than the US, but it has significantly fewer slower connections (under 4Mbps) and slightly more fast connections (above 15Mbps) on a percentage basis.
The shape of the distribution curve and what the typical user gets that IMHO are more significant than the mean.
