How Netflix streams videos

When you hit ‘Play’

Netflix uses the most efficient path possible to carry video through our system to your internet service provider (ISP). We route your video to avoid heavy internet traffic or problems.

We have servers all over the world, and send your video stream from as close to you as possible. The shorter the route, the higher the video quality.

From ISP to home

When Netflix hands off your video to your ISP, it goes through their network to your home.

If there are no major roadblocks, your ISP delivers the video right to your screen.

Video quality depends on several factors, including:

  • Your ISP’s connection to your home

  • Your modem or router

  • The number of connected devices in your household

  • Other activity on your internet connection

Help when you need it

Congestion on any part of the connection between Netflix and your screen can cause streaming problems that affect video quality.
