Surf Speed Test

Advertised speeds are “up to” peaks measured on an ideal connection. Real-world speed to a neutral point on the open internet runs a few percent lower, and Wi-Fi, older equipment, or peak-hour congestion lower it further. For the truest read of your Surf line, test over a wired connection.

Tests run against the nearest of Cloudflare’s edge locations, so the result reflects your access network rather than a server inside Surf’s own network. We verify each result by network operator, aggregate it as a median (not an average, which a few fast tests would skew), and only publish a provider’s measured speeds once enough independent tests exist. We do not accept provider-submitted numbers.

Run the test above. The connection-quality grade reads latency under load and packet loss, which determine whether calls and games stay smooth, beyond the raw download number.
