Internet Speed Test
Measure your real-world internet speed using Cloudflare's global network.
Network Analysis
A speed test measures your connection to a test server to determine how fast your internet connection is capable of transferring data. This helps you verify if you're getting the speeds promised by your ISP.
Performance Metrics
Your download speed shows how fast you can receive data, upload speed shows how fast you can send data, and ping indicates the latency or delay of your connection.

Why is my speed slower than what I pay for?
Many factors affect speed: WiFi interference, distance from router, network congestion, and the 'up to' nature of ISP speed claims. Wired connections typically show faster speeds.
What is a good internet speed?
For most users: 25+ Mbps for HD streaming, 50+ Mbps for 4K streaming, 100+ Mbps for gaming and multiple devices. Ping under 50ms is ideal for gaming.
Why does Cloudflare speed test matter?
Cloudflare handles traffic for millions of websites. Testing against their network gives you a realistic measure of your everyday browsing experience.
