Depends.  If the current gear had enough capacity to absorb the additional
50%, the ISP's costs didn't change. You were blowing 6Gbits/sec down a
10G pipe, and now you're pushing 9, you don't care.

On the other hand, if you were pushing 8 and now need to push 12, you
may have just bought a very expensive forklift upgrade to 40G.

Drastically oversimplified, of course.
