We've just opted out of our brand new LGfL 2 connection (less than a year old!) and are currently in the process of having a new connection from M247 installed. We found that our local RBC was just too restrictive, too expensive compared to going it alone and offered services we just weren't interested in.

I can understand how some schools (in particular primaries) would benefit from the services RBCs offe, but certainly for a school like ours going it alone is just better, easier and cheaper for a faster, more redundant connection.
