BT Internet Speed Test Results

We analysed users testing BT Broadband multiple times, each test starting no more than 30 minutes after the previous speed test. On average, BT customers ran 4 speed tests per session. Looking at download speeds, if the download speed of a BT 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 BT 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 BT's customer base, of the speed tests we measured, 39.62% were fast, 24.03% slow, and 36.35% broadly the same.
