Coriolis Broadband Speed Test Results

We analysed users testing Coriolis multiple times, each test starting no more than 30 minutes after the previous internet speed test. On average, Coriolis customers ran 4 speed tests per session. Looking at broadband download speeds, if the download speed of a Coriolis user'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 consider this a customer Coriolis should speak to as soon as possible. For speed tests that don't vary by that much, we consider the final result to be the same. For Coriolis's customer base, of the speed tests we measured, 42.13% were fast, 28.93% slow, and 28.93% broadly the same.
