  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.
