For the past month or so, there have been roadworkes/chorus workers etc on my street fucking with the main internet line that runs up it, and putting a few roadside cabinets in. For the past 2 weeks or so, they have been sitting at the cabinets configuring them...
This morning, I went to download World of Tanks, which is about 1GB, and it finished in 5 minutes.
Puzzled, I checked speedtest...

Fucking. Sweet.
Note: As of yesterday I was getting 2Mb/s down.
