"Competition is meant to benefit consumers,
and not create obstacles for them. The record shows that customers experiencing
service disruptions generally blame their provider, even if the problem is
caused by an incumbent. Indeed, Z-Tel states that one glitch or delay in the
cut over process for a mass market customer may be enough to convince the
customer to go back to the incumbent."
