Average Internet Speed in Sri Lanka

Internet in Sri Lanka: what the data shows

At a median 9.9 Mbps download, Sri Lanka sits near the back of the field: #102 of 119 ranked countries, well under half the global median of 33.9 Mbps. The world's fastest median belongs to the United States at 144 Mbps, more than 14× the speed measured here.

The median upload is 5.6 Mbps, about 57% of the download rate: the balance typical of a market mixing fibre with cable or DSL plans. Median latency is 100 ms. That is on the high side: pages and video still load, but calls, gaming and screen sharing carry a visible delay.

The fastest measured provider, SLT at 16 Mbps, sits close to the national median: providers cluster tightly here, so the plan tier you buy matters more than which network you pick.

Phones out-test desktops (10 vs 9 Mbps), a mobile-first pattern: cellular networks often outrun the fixed lines here, and mobile devices run 69% of tests. By operating system, Android devices record the quickest median (10 Mbps) while Windows sits at 6 Mbps, usually a proxy for the networks and hardware each platform rides on rather than the software itself.

Tests from Sri Lanka most often reached the Singapore test server (100% of the top-server mix), so the figures reflect the routes everyday traffic actually takes. Every number on this page is a median of single-stream browser tests from the H1 2026 window: Real-World Speed, measured on the open internet rather than inside an ISP's own network. It reads lower than peak-rate tests by design, and every country is measured with the same ruler.
