Pong.com vs Fast.com
Fast.com shows you a download number. Pong.com shows you the full picture: upload speed, bufferbloat grades, connection health scores, real-world experience ratings, and more. Here's how they compare.
Feature Comparison
A side-by-side look at what each speed test measures and offers.
Fast.com is a download number, not a connection report
Open fast.com in any browser and you will see one number: download speed. Everything else is hidden behind a "Show more info" button. That single click is the difference between a marketing metric and a useful diagnosis.
These are observable on the live site at fast.com. No upload speed is shown by default. No unloaded latency. No loaded latency. No jitter measurement at all. No bufferbloat detection. No packet loss reporting. No server selection: every test runs against Netflix's own delivery infrastructure.
Fast.com is built around Netflix's specific content delivery architecture, which is optimized for streaming a single large file to a single client. That is a narrow shape of internet traffic. Real connections also carry video calls, online gaming, voice conferencing, file uploads, and dozens of small parallel requests, all of which depend on upload bandwidth, latency stability, and router buffer behavior. Reporting only download speed can underrepresent how a connection actually performs day to day.
For SEO-savvy readers, fast.com's page itself is also a study in minimalism: a roughly 30 character title tag, no H1 heading on the page, no FAQ schema, and almost no on-page text content. That works as a brand statement, but it leaves users without the context they need to interpret a result, and search engines without the structure they need to surface the page for related questions.

Key Differences
Fast.com is simple by design. Pong goes deeper with diagnostics that explain why your connection feels the way it does.
What Pong Measures That Fast.com Doesn't
Download speed is just one piece of the puzzle. These metrics reveal the full health of your connection.
Bufferbloat Detection
Measures latency under load to detect router buffer issues. Graded A through F so you know exactly how your connection handles heavy traffic. This is the #1 cause of lag that traditional speed tests miss.
Jitter Analysis
Goes beyond a single number. Pong analyzes the variance in your ping times to show how stable your connection really is. High jitter causes stuttering in video calls and rubber-banding in games.
Connection Health Grades
Get an overall A through F grade for your connection based on speed consistency, latency stability, bufferbloat severity, and Wi-Fi quality. One score that tells you if your internet is actually healthy.
Real-World Experience Scores
Know whether your connection can actually handle 4K streaming, competitive gaming, video conferencing, and general web browsing. Not theoretical maximums, but scores based on your actual test results.
Streaming Quality Estimator
Tells you the maximum streaming resolution your connection supports right now. See if you can handle 4K, 1080p, or 720p based on your actual bandwidth, latency, and bufferbloat results.
Wi-Fi Diagnostics
A rapid-fire 30-ping burst test that detects Wi-Fi interference, signal instability, and connection drops. Identifies whether your Wi-Fi is the bottleneck, not just your ISP.
How Pong Tests Differently
What gets tested and how it gets tested both matter.
Fast.com's Approach
Fast.com was built by Netflix as a quick way to check download speed. It uses Netflix's own CDN servers for testing, which gives you a good measure of how fast you can download from Netflix specifically. Upload speed and latency are available but require clicking "Show more info." There is no bufferbloat testing, no jitter analysis, and no connection health scoring.
Pong.com's Approach
Pong.com tests through Cloudflare's global edge network with 300+ points of presence, plus 10 dedicated test servers worldwide that you can select. Every metric is shown upfront: download, upload, ping, jitter, bufferbloat, and connection health grades. You also get real-world experience scores that tell you how your connection performs for gaming, streaming, and video calls.
