If the ISP is checking for DNS lookup of speed test websites, then allocating higher bandwidth to the connection for a brief period of time?
Or, somehow more cynically, the ISP makes money from selling the data collected from DNS, so punishes people who use a different DNS provider. (DNS is plaintext-by-default, so I don't quite see how this would work, but it's possible.)
Or perhaps the system uses DNS lookups as a proxy for “is a human browsing the web”; if there aren't enough, it's clearly some kind of automated computer program that doesn't deserve internet access.

- wizzwizz4 5y agoThe first example is a real-life example. The other two are speculative, because I've heard a case where it wasn't the first example.
