Possible disadvantages

  • Limited Metrics
    Fast.com primarily focuses on download speed and does not provide as comprehensive a range of metrics as some other speed test websites, such as upload speed, latency, and jitter.
  • No Server Selection
    Users cannot choose which server to run the speed test against, which can sometimes result in less accurate measurements for specific network conditions.
  • No Historical Data
    Fast.com does not offer features to save or track historical speed test results, limiting users' ability to monitor their internet performance over time.
  • Lack of Customization
    There are no options to customize the test parameters, such as test duration or concurrency levels, which might be relevant for more advanced users.
  • Geared for Streaming
    Since Fast.com is tailored for Netflix streaming, it may not fully represent other usage scenarios, such as gaming or file downloads, which require different network performances.

  • I Built a Fast.com for LLMs: Introducing iamspeed.dev
    That is exactly how fast.com works for internet speed tests. You open it, it runs, you see a number. Done. - Source: dev.to / 4 months ago
  • Streaming the 2026 Winter Olympics: A Developer's Guide to Live Sports IPTV
    Pro tip: Run a speed test immediately before the event. Don't trust your "up to 100 Mbps" ISP claim. Use fast.com or speedtest.net to get real numbers. - Source: dev.to / 7 months ago
  • Downdetector, Speedtest sold to IT service provider Accenture in $1.2B deal
    Speedtest has always seemed incredibly sketchy to me, I don’t know if others share this sentiment. https://fast.com completed the test faster than speedtest loads the site. - Source: Hacker News / 7 months ago
