Guyancourt Internet Speed Test Results

We analysed the results of people in Guyancourt testing broadband providers multiple times, with each test starting no more than 30 minutes after the previous speed test. On average, people in Guyancourt ran 4 internet speed tests per session. Looking at broadband download speeds, if the Guyancourt resident's final test is 10% faster than their starting download speed, we count that as a succesful and faster speed test result. We count an unsuccessful, slower result if the final result is 10% slower than the starting result; we'd hope their ISP contacts them ASAP! For broadband speed tests that don't vary by that much, we consider the final result to be the same. For Guyancourt's residents, of the internet speed tests we measured, 45.65% were fast, 28.99% slow, and 25.36% broadly the same.
