Sri Lanka Internet Speed Test

Free, no-signup internet speed test. Measures your download, upload, ping and jitter against our Singapore server — the route most international content (YouTube, Facebook, Netflix) takes to reach you.

How to test your internet speed in Sri Lanka

Click Start Speed Test above. The test runs entirely in your browser and takes about 30 seconds. It measures four things:

  • Download speed — how fast data reaches you from the internet
  • Upload speed — how fast you can send data out
  • Ping — round-trip time, the lag you feel in video calls and games
  • Jitter — ping variability, which makes calls choppy if high

What speeds should I expect on a Sri Lankan connection?

Speeds vary by ISP, plan, and time of day. As a rough guide:

  • SLT Fibre — 21 Mbps to 1 Gbps depending on plan
  • SLT ADSL / VDSL — 4 to 100 Mbps
  • Dialog 4G LTE — typically 10–60 Mbps download
  • Dialog Home Broadband (Fibre) — 25 Mbps to 1 Gbps
  • Hutch 4G / Airtel 4G — 5–40 Mbps depending on cell coverage
  • Mobitel 4G — 10–50 Mbps in urban areas

Evening peak hours (7–11 pm) typically slow connections by 20–40% as networks get congested. Speeds to Singapore (this test's server) reflect what you'll experience for most international websites and streaming services, since major CDN traffic from YouTube, Facebook, Netflix, and similar services routes through Singapore or Mumbai.

Why is my internet slow?

Common causes for slower-than-expected speeds in Sri Lanka:

  • Wi‑Fi vs wired — Wi‑Fi can cut speeds by 50% or more. Try plugging in via Ethernet for a comparison.
  • Distance from the router — thick walls and 2.4 GHz interference matter.
  • Time of day — evening congestion is real, especially for 4G and shared ADSL contention ratios.
  • VPN active — VPNs add 30–200 ms of ping and can halve your throughput.
  • Cable damage / faulty modem — the SLT or Dialog technician test will rule these out.
  • International undersea cable cuts — SEA‑ME‑WE 4/5 issues occasionally bottleneck Sri Lankan traffic to Singapore.

About the test server

This speed test connects to our server in Singapore. The path from Sri Lanka to Singapore travels via the SEA‑ME‑WE undersea fibre cables and is typically 60–90 ms of latency. Most international websites, streaming services, and gaming servers reach Sri Lankan users through Singapore or Mumbai, so this test is a realistic measure of your everyday internet experience.

We log results (download/upload speeds, ping, ISP, location, IP address, and timestamp) to build aggregate “average speed by ISP” statistics for Sri Lankan readers. See our Privacy Policy for details.
