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 C Spire
C Spire's fastest available plans reach 10,000 Mbps down / 10,000 Mbps up, and across its footprint typical available speeds are about 3,152 Mbps down / 3,107 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 C Spire line actually delivers.

C Spire Speed Test FAQ
Why is my C Spire 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 C Spire line, test over a wired connection.
How does ISPReports measure C Spire speeds?
Tests run against the nearest of Cloudflare's edge locations, so the result reflects your access network rather than a server inside C Spire'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 C Spire 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.
