Eighty-four percent of Internet Service Providers (ISPs) decreased 0.2 Mbps and 15 percent stayed the same, resulting in a lower average speed this month on the Netflix ISP Speed Index, a monthly update on which ISPs provide the best prime-time Netflix streaming experience.

These are considered normal moves, Netflix said in a statement, as it rolls out new encodes and titles.

There were no significant ISP gains or notable changes to country averages. However, 88 percent of countries moved down 0.2 Mbps following the previously mentioned bitrate trend.

Three ISPs dropped 0.4 Mbps since January’s results. CableColor in Guatemala and Optix in Pakistan fell from 2.8 to 2.4 Mbps. TEVISAT in Honduras decreased from 2.4 to 2.0 Mbps, the streamer said in a statement.

Thirty-one countries and regions were in the top performance tier for February. These nations included Australia, Belgium, Canada, Denmark, Finland, France, Germany, Hong Kong, Hungary, Iceland, India, Ireland, Israel, Luxembourg, Malaysia, Netherlands, New Zealand, Norway, Panama, Paraguay, Portugal, Romania, Singapore, South Korea, Spain, Sweden, Switzerland, Taiwan, Thailand, United Kingdom, and the United States, all registered an average speed of 3.0 Mbps.

The streamer’s ISP Speed Index is a measure of prime-time Netflix performance on a particular ISP and not a measure of overall performance for other services or data that may travel across the specific ISP network. Higher Netflix performance generally means better picture quality, quicker start times, and fewer interruptions.
