Frontier has gone the other way. The service here was 3mbps but they oversold the service and backed it down the 1mbps. It isn't often that the full 1 mbps is seen. It is more like .25-.5 mbps with pings late at night around 100-500 ms and daytime/evening around 1000-1700 ms. Secure sites are impossible to use most of the time.
