Now compare your speed to the providers available at your address.
See providers at your address →How we measure: a real-world test to a neutral point on the open internet, not a server inside your provider network, so it reflects everyday speed and can read slightly below best-case on-network tests.
We record anonymized results (speed, latency, your provider and coarse location) to publish honest, real-world speed data by provider. No personal information is stored.

What to Expect from CNS
CNS's fastest available plans reach 1,000 Mbps down / 1,000 Mbps up, and across its footprint typical available speeds are about 51 Mbps down / 21 Mbps up. These are advertised “up to” figures from FCC availability data, so no connection reaches them exactly. Run the test above to see what your own CNS line actually delivers.

Compare providers near you
Enter your ZIP or city to see how providers in your area compare.
Providers available in your area come from our coverage data. "Available up to" is the fastest advertised plan; measured speeds appear once a provider has enough independent tests, otherwise we say "collecting" rather than guess.

CNS Speed Test FAQ
Why is my CNS speed lower than advertised?
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 CNS line, test over a wired connection.
How does ISPReports measure CNS speeds?
Tests run against the nearest of Cloudflare's edge locations, so the result reflects your access network rather than a server inside CNS'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.
Is CNS good for gaming and video calls?
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.
