Who made best speed internet in the world?

Last week, Aaron said S.Korea has #1 speed internet, and the rank still did not change yet. .
The

"Top Countries by Download Speed" from speedtest.net shows S.Korea's Internet speed is still fastest one. Who made the fastest internet in the world then? There are several Cable service companies in Korea, and I believe that KT is the biggest cable company in Korea. I just read an article from Koreantimes, and KT was #1 internet service provider in 2007, and I am pretty sure that KT is still #1 after they brought KT Wibro(it is like Wifi). Like TimeWarner or Verizon in U.S., KT is now offering variety service all together that has internet+cable+phone, and KT is becoming more powerful after affilating with KTF mobile company.

Showing AD is one of their internet and cable TV service called "QOOK" AD on air, and KT attracts more customers by it.
