Telus [Canada] Explains Why UBB will Start on March 30

  
A year after Telus started experimenting usage charges (see "Telus to Start Charging for Usage ("it is fair")"- here) the change becomes a national policy for the Canadian operator's fixed ISP services, on March 30.

The surcharge will be automatic, but notifications to customers getting closer to the limit will start on an undefined date in the future.
