1&1 Internet Speed Test Results

We analysed users testing 1&1 Internet multiple times, each test starting no more than 30 minutes after the previous speed test. On average, 1&1 Internet customers ran 3 speed tests per session. Looking at download speeds, if the download speed of a 1&1 Internet 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 1&1 Internet 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 1&1 Internet's customer base, of the speed tests we measured, 40.74% were fast, 37.04% slow, and 22.22% broadly the same.
