After http://www.dsl-discounter.de is offline and using my flat from dsl-discounter I finally switched to 1&1
It seems to be faster than dsl-discounter and support webpages are very good. Everything seems to be configurable, even a cost limit is configurable! Also a domain seems to be included in the flat for no additional costs, but this needs further examination — I don’t want to pay more than the 20 euro per month.
I’m considering posting more in my blog — should I?
