Introduction
We received from a visitor measurements at 250 Mbps 🙏. Hence the speed to measure is 252 (or 280) Mbps Almost all speed tests mentioned at My speed test results were tested three times! Again 🙏.
The measurements
All speeds measured are in Mbps.

Conclusions
Based on the measurements above it can be concluded that:
- Three speed tests (Real Speed, Speedtest and Fireprobe) have an accuracy score of 100
- One speed test (SpeedOf.me) has an accuracy score of 99
- Six speed tests are recomended at 250 Mbps
- Google Fiber apparently failed completely
The best speed tests at 250 Mbps are:
