As proverbs saying "It's like the shadow of the light", it is early that time passes, and it is March 2018.

ISP SPEED INDEX (JAPAN)

From 19 o'clock to 23 o'clock, the number of people who use the Internet increases, which is especially crowded. Depending on the connection environment, even if you try to play the net after going home, you get crowded and the speed does not come out at all, the web site does not open, even if you are in a movie site such as YouTube you can not finish reading. Therefore, it is better to contract with an ISP whose speed is stable even in the night when the net is congested easily. However, unless you actually contract and connect to the Internet, it is hard to understand which ISP can provide a stable speed.

The data in "ISP Speed ​​Index" is the average bit rate when users view Netflix contents at the most busy time, measured at megabits per second (Mbps). The results measured every month are summarized by country, and furthermore it is published in the ranking format by ISP in the country.

For example, in January 2018Ranking in Japan, And the average bit rate during the golden time are as follows.
First place:au hikari (au one net)...... 4.06 Mbps
Second place:UCOM...... 3.58 Mbps
3rd place:eo light...... 3.48 Mbps
4th:IIJ...... 3.37 Mbps
5th place:TOKAI Communications...... 3.34 Mbps
6th place:OCN...... 3.29 Mbps
7th place:ASAHI net...... 3.27 Mbps
8th place:iTSCOM...... 3.26 Mbps
9th place:J: COM...... 3.25 Mbps
10th:So-net...... 3.23 Mbps
11th place:VECTANT...... 3.20 Mbps
12th place:BIGLOBE...... 3.20 Mbps
13th place:Softbank Light...... 3.11 Mbps
14th place:@ Nifty...... 2.76 Mbps
15th place:InfoSphere...... 2.62 Mbps
16th place:Yahoo! BB ADSL
17th place:au one net(Other than optical line) ...... 2.46 Mbps
18th place:freebit...... 2.44 Mbps

You can also check the transition of the average bit rate by ISP. Data is recorded for 2 years and half after September 2015 when Netflix started service in Japan, ISP to be displayed can be switched by oneself. The top five ISPs of the rankings are displayed in the following images. The top au Hikari, somehow starting data collection in October 2016, has been keeping the leaders forever. However, it is downward as a whole.


Since conditions other than Japan have been released, I tried to display the top five ISPs in the US for the same period as those in Japan. In Japan, the average bit rate was quite up and down every month, but in the U.S. there are few up and down movements, especially the top four companies consistently keeping the speed of less than 4 Mbps.


Every ISP appeals high cost performance and abundant service, but if you sign up and use it, it may happen that at peak time, the speed drops drastically and it will not connect at all. Netflix officially provides all the data at peak time and never compares the overall performance of ISP directly, but because it can be said that it is fairly practical data, ISP transfer for a new life It is good to try people who are considering.
