Worksop (Sheffield). The strangest thing was, I found a site (post a link in a sec) where you can enter your ISP, what package you have, and your postcode, and it will give you an estimated maximum speed (3MB for me). However it also tells you where your local exchange is, and for me it said Worksop which is where I live. If that is actually true, and considering Worksop is about 2 square miles, then surely I should be able to get near enough the maximum speed? It must be wrong, the exchange can't be that close.
Here's the site I was on about anyway:
