    Some users may prefer a speed test that is vendor-neutral, rather than one operated by a specific CDN company like Cloudflare.
  • Potential Bias
    As a Cloudflare operated service, test results might be optimized for Cloudflare's network, potentially not reflecting performance on other services or networks.
  • Relatively New
    Compared to longstanding services like Ookla's Speedtest.net, Cloudflare's speed test is relatively new and might not have the same level of historical data and long-term reliability.
