I think he has already explained that it is not possible for him
to buy bandwidth from both providers in both cities. Therefore, your

IIRC, he has also already explained that he already has a backup
pipe between the two sites. However, because he can't buy bandwidth
from both providers in both cities, this obviously is only part of
the equation.
