Conclusions

Based on the measurements above it can be concluded that:

  1. Three speed tests (Real Speed, Speedtest and Fireprobe) have an accuracy score of 100
  2. One speed test (SpeedOf.me) has an accuracy score of 99
  3. Six speed tests are recomended at 250 Mbps
  4. Google Fiber apparently failed completely

The best speed tests at 250 Mbps are:

  1. Real Speed
  2. Speedtest
  3. SpeedOf.me
