What is the Internet Speed Test?
This internet speed test measures what your connection actually delivers right now. It runs in your browser, opens several parallel connections to a nearby test server, and reports your download speed, upload speed, ping (latency), jitter (how steady the ping is) and ping under load, which shows whether your line stays responsive when it is busy.
Speeds are shown in megabits per second (Mbps), the unit internet providers advertise, and can be switched to megabytes per second (MB/s), the unit your browser shows for downloads. Results are compared with real-world needs such as HD and 4K streaming, video calls, online gaming and live streaming, so you can see at a glance whether your plan is good enough. Every test is saved in your own browser so you can compare morning and evening, Wi-Fi and cable, or before and after calling your provider.

Questions people ask
How does this speed test work?
Your browser downloads and uploads test data over several parallel connections for a few seconds and measures how many bits arrive or leave per second, after a short ramp-up period. Ping is measured with small requests and reported as the lowest round-trip time.
Why is my result lower than my plan?
Advertised speeds are maximums to your provider. Wi-Fi, distance from the router, older devices, a VPN, other people online and the test server itself all reduce the measured speed.
What is a good internet speed?
Around 25 Mbps handles 4K streaming for one person, 100 Mbps suits most households, and 300 Mbps or more is comfortable for many devices, large uploads and cloud gaming.
What are ping and jitter?
Ping is the time a small message takes to reach the server and come back; jitter is how much that time varies. Low and steady numbers matter most for calls and games.
What is ping under load?
It is your ping while the line is downloading at full speed. A big jump means bufferbloat: your router queues too much data and everything feels laggy while someone downloads.
