Southwark Internet Speed Test Results

We analysed the results of people in Southwark testing broadband providers multiple times, with each test starting no more than 30 minutes after the previous speed test. On average, people in Southwark ran 4 internet speed tests per session. Looking at broadband download speeds, if the Southwark 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 Southwark's residents, of the internet speed tests we measured, 42.11% were fast, 27.69% slow, and 30.2% broadly the same.
