Netflix ISP Speed Index for January 2018

Updated Feb. 14, 2018: An earlier version of this blog post included the wrong speed value for Swisscom. The correct speed value is 4.21 Mbps. Since this no longer reflects a significant speed gain, the Swisscom statement was removed.

Here are some highlights from the January data for the Netflix ISP Speed Index, our monthly update on which Internet Service Providers (ISPs) provide the best primetime Netflix streaming experience.

South Korea’s D LIVE had the largest speed gain in January, gaining by 0.59 Megabits per second (Mbps). This increased its average monthly speed to 2.84 Mbps, up from 2.25 Mbps in December. Other gains include AIS in Thailand, gaining 0.45 Mbps to an average of 4.45 Mbps, and Netvision in Israel, gaining 0.30 Mbps to a 3.35 Mbps average.

There were several notable speed losses on the index this month in Saudi Arabia, the Asia-Pacific region and others.

Saudi Arabia’s STC experienced the largest loss on the index this month (at 0.70 Mbps), decreasing its monthly average to 2.17 Mbps, down from 2.87 Mbps in December. This loss and others contributed to Saudi Arabia’s nine-spot drop to 54th in our country rankings.

In Asia, ISPs in Indonesia, Malaysia and Taiwan saw speeds slow in January:

• In Indonesia, Indosat-Fibre’s speeds declined to a 3.69 Mbps average (from 4.26 Mbps in December) and Neuviz’s saw speeds slow to a 1.80 Mbps average (from 2.26 Mbps).
• Malaysia dropped 15 spots to 38th in our country rankings. Telekom Malaysia Berhad’s speed loss of 0.64 Mbps contributed to the drop.
• Taiwan dropped 5 spots to 31st in our country rankings. KBro’s speed decline to a 3.05 Mbps average (down from 3.40 Mbps), among others, contributed to the drop.

Additionally, there were significant speed losses in other countries:

• Hargray in the United States saw speeds decrease to a 2.41 Mbps average (down from 2.89 Mbps in December).
• Wind Hellas in Greece saw speeds slow to a 2.62 Mbps average (down from 3.03 Mbps).
• ETB in Colombia saw speeds decrease to a 2.54 Mbps average (down from 2.94 Mbps).

The Netflix ISP Speed Index is a measure of primetime Netflix performance on a particular ISP and not a measure of overall performance for other services/data that may travel across the specific ISP network. Faster Netflix performance generally means better picture quality, quicker start times and fewer interruptions.
