While measuring your download speeds are fine and dandy, there are other factors that come into play when it comes to your internet connection. Fast.com, Netflix’s free speed test service, now measures upload speed and latency in addition to the download speed you’re getting from your internet service provider.
Upload speed is pretty straightforward and measures the speed of the connection for uploading data from a user’s device to the internet. Latency, on the other hand, is something you may not have heard of if you’re not a techie.
Latency refers to the time it takes for data to travel from a user’s device to the server and back – will be measured on both unloaded and loaded connections. Unloaded latency measures the round-trip time of a request when there is no other traffic present on a user’s network, while loaded latency measures the round-trip time when data-heavy applications are being used on the network.
Fast.com was launched about two years ago and has already reached half a billion speed tests. Half of those (250 million) were conducted in the past seven months. The site was launched by Netflix in an effort to provide transparency with the speeds that ISPs claimed they were providing and the actual speeds that end users were getting, especially when using streaming services.
