Are there any maps online indicating ADSL and cable coverage for Switzerland?

I don't know of any maps, but this site here allows you to enter the phone number of the place where you are (or will be) and tells you if you get ADSL there and how fast...

generally, I'd say that ADSL is available nearly everywhere (I don't know of a single place where it's not available by now). Cable coverage is a bit less well spread.

Thank you. Great news.

Makes you wonder why coverage is still not complete in the UK.

Et Cable brutus?

Gratias citizen.
