We're Making Fast Even Faster

I received an e-mal with the subject line I've used above, telling me that my speed was going to be increased significantly.  I was fine with the speed I had, but, OK.

However my speed has gone up slightly... some of the time.  At other times it is significantly lower, and I'm not even able to get through a 20 minute video without several pauses, which never happened before.  Is this making fast 'faster"?
