Granted I never said it was good or bad, just stating a standard and proper large network, either it be in a large building or external, should have redundancies.

If a fiber line is cut, internet can continue flowing through other means until repair can make it out, either that is under an hour, or the next day. Out here in rural NW Oklahoma, if a line is damaged, and it's been raining heavily or snow/ice build up, you're lucky to get someone out there within an hour just to see the cause.
