Well, this has basically rendered the 20mb connection useless for me. I work from 2pm till 10pm, and as such the STM wasn't affecting me in the slightest because I did all my downloading in the mornings, but now the 10am till 3pm STM has put a stop to that. Basically the only time I can download without worrying about hitting STM is overnight, and in that case it makes no difference if the connection is 4mb or 20mb, it'll still be done by the morning.
I've just called up and dropped down to 4mb (free upgrade to 10mb by the end of the summer) and saved £15 a month.
Not happy though
