I am not sure what is going on here, but I just saw the thread about the new Speed Test servers, so tried it out — as you would. My VDSL2 connection was giving me 36 and 6 after instal, which gradually came down to 29 and 5 over six months or so. Now I am suddenly getting 46.5 and 5.8! I always used Speed Test.
Is this to do with the new speed test servers rather than an actual performance gain, or has something happened to boost our connection? I am on the Spring Creek Exchange north of Blenheim, and effectively 1k from the cabinet at the top of Hammerichs Road.
