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 CMS Internet

CMS Internet's fastest available plans reach 1,000 Mbps down / 1,000 Mbps up, and across its footprint typical available speeds are about 378 Mbps down / 290 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 CMS Internet line actually delivers.

CMS Internet Speed Test FAQ

Why is my CMS Internet 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 CMS Internet line, test over a wired connection.

How does ISPReports measure CMS Internet speeds?

Tests run against the nearest of Cloudflare's edge locations, so the result reflects your access network rather than a server inside CMS Internet'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 CMS Internet 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.
