Our broadband connection has been inexplicably slow for a number of days, to the point of being unusable. Of course broadband support is never helpful and says it is all our fault. After many conversations they suggested I should run the speed test at speedtest.bt.com.
I had already run a couple of other speed tests from different websites, however immediately after this test my broadband speed was restored. Broadband support is telling me this was 'purely coincidental', however I don't buy it and am interested in how this 'test' could have had the 'coincidence' it did?
