We also had some providers that blocked ports but I think no one does it anymore over here
as all the customers ran away from them

I once thought I could try KabelTV (which gives you here next to TV a 32mbit DSL line)
but limited traffic and together with TV it was much too expensive.
I would be bankrupt if I had to pay for extra traffic
as I usually have between 50GB and 400GB / month
OH NO just some minutes ago
I got a new offer from my provider today:
VDSL (up to) 50mbit (51.300) down and 10mbit up
including all the other stuff I already have and some more things for 49,99 Euro.

Damn! 50 down and 10 up
now I really start to think about it.
