About These ISP Speed Rankings
These rankings are built entirely from real user speed tests — no synthetic benchmarks, no lab conditions. Every result you see here came from an actual device on an actual connection, tested through Speedtest.now. Rankings update daily and use a rolling 7-day window so recent changes in network performance are reflected quickly.
How ISP Detection Works
ASN Lookup
Each test records the client IP address. We resolve that IP to its Autonomous System Number (ASN) — the unique identifier assigned to every ISP and network operator worldwide.
Reverse DNS
Reverse-DNS lookups map the IP to a hostname, which typically includes the ISP's domain (e.g. cable.virginm.net). This cross-referenced with the ASN record gives a reliable ISP name.
Median Scoring
We use the median rather than the mean to resist distortion from outliers. A single user testing on a 10 Gbps research line won't inflate an ISP's score — the middle value of real-world results is what counts.
Minimum Sample Threshold
ISPs need at least 5 test samples in the rolling 7-day window to appear. This prevents a single test run from creating a misleading ranking for a small or newly-listed provider.
How to Read These Results
Download Speed
How fast data arrives at your device. Affects streaming quality, web page load times, and file downloads. Higher is better.
Upload Speed
How fast data leaves your device. Critical for video calls, cloud backups, live streaming, and remote work. Higher is better.
Ping (Latency)
Round-trip time for a packet to reach the test server and return. Determines responsiveness for gaming, VoIP, and real-time apps. Lower is better.
Samples
The number of tests contributing to the 7-day median. More samples mean a more statistically reliable result. ISPs with low sample counts may have higher variance.
Why ISP Performance Data Matters
Choosing a Provider
Advertised speeds are maximums under ideal conditions. Real-world medians from this table tell you what customers are actually experiencing at home during typical usage hours — a far more honest number to comparison-shop with.
Benchmarking Your Connection
If your ISP ranks highly but your personal tests are far below the median, that signals a local issue — router placement, old cabling, congested Wi-Fi, or an equipment problem on your line. Use this data to set your baseline expectations.
Holding ISPs Accountable
Crowd-sourced, independent speed data creates public accountability. If an ISP's real-world median drifts well below its advertised tier over time, that discrepancy becomes visible and documented here.
Spotting Network Congestion
Because rankings update daily, sudden drops in an ISP's median can indicate network congestion, maintenance, or infrastructure problems. Regular testers in the same region tend to see these shifts in real time.
Frequently Asked Questions
Why isn't my ISP listed?
ISPs must accumulate at least 5 tests in the past 7 days to appear. Smaller regional providers may not yet have enough tests from users in your area. Running a test yourself contributes to your ISP's sample count.
Does time of day affect rankings?
Yes. Tests run during peak hours (evenings, weekends) typically produce lower speeds due to network congestion. The 7-day median naturally blends peak and off-peak results, giving a more balanced picture of typical day-round performance.
Can ISPs game these rankings?
Our fraud detection filters out scripted, automated, and anomalous results. Tests flagged as non-genuine are excluded from ranking calculations. The crowd-sourced nature of the data also makes it difficult to inflate — you'd need thousands of real unique users to meaningfully shift a median.
How often do rankings change?
Rankings are recalculated daily. As new tests are added and old ones drop out of the 7-day window, positions shift. High-traffic ISPs with large sample counts tend to be more stable; smaller ISPs with fewer daily tests can move more noticeably.
