Internet Speed Test

Measure your connection's download and upload throughput, latency and jitter with LibreSpeed, a widely used open-source speed test. Real data is transferred between your browser and our test server for up to 10 seconds in each direction. Results are calculated from the bytes actually transferred – nothing is estimated or simulated.

Tool status: Functional with limitations Works, but there are technical limits explained on the page.

Measured against IPandNet server (Hostinger) using LibreSpeed (open source, LGPL v3). Results cannot exceed what this server can send and receive.

What this tool can and cannot do

Results measure the path between you and our test server. A speed test can never be faster than the slowest link: your Wi-Fi, your ISP, the route across the internet, or the test server's own connection. Our test server currently runs on shared web hosting, so on fast connections the server – not your line – may be the limit, and to protect the website only a few tests can run at the same time (you will see a “server busy” message if all slots are in use). The test can use a few hundred megabytes on fast connections – keep this in mind on metered mobile data. Speeds are reported as the actual data rate delivered, with no added allowance for protocol overhead, so they may read a few percent below your plan's advertised line rate.

Understanding the results

Download (Mbps) is how fast data reaches you – what matters for streaming, browsing and downloads.

Upload (Mbps) is how fast you can send data – important for video calls, cloud backup and live streaming.

Ping is the round-trip time in milliseconds for a small request. Lower is better: under 30 ms feels instant; over 100 ms can be noticeable in games and calls.

Jitter is how much ping varies from one request to the next. Low jitter (under 10 ms) means a stable connection for calls and gaming.

Our ping is measured using HTTPS requests, so it is usually a few milliseconds higher than a traditional ICMP ping.

Troubleshooting

  • Run the test on a computer connected by Ethernet cable to rule out Wi-Fi problems.
  • Pause downloads, cloud sync, streaming and updates on other devices during the test.
  • Test at different times of day: evening slowdowns usually indicate network congestion at your ISP.
  • If speeds are consistently far below your plan on a wired connection, restart your router and modem, then contact your ISP with your results.

Frequently asked questions

Why is my result lower than my plan speed?

Plans advertise a maximum "up to" speed. Wi-Fi, older devices, browser overhead, busy times and the distance to the test server all reduce the measured result. A wired test at a quiet time gives the most representative number.

Why do different speed tests show different results?

Each service uses different servers in different locations and different measurement methods. Compare results from the same test over time rather than across services.

How much data does a speed test use?

Roughly speed × duration. A 100 Mbps connection transfers about 125 MB in 10 seconds of downloading, plus the upload portion.

What speed do I need?

As a rough guide per simultaneous activity: HD video 5–8 Mbps, 4K video 15–25 Mbps, video calls 2–4 Mbps up and down. Households with several users need the combined total.
