Not so rarely Priscilla if we talk about fiber, I have to deal with that problem 3 or 4 times a year, unfortunately it's quite easy to damage only partially a fiber optic cable when a hospital is repairing any wall, disposing a room, ... (and they are always doing that sort of things!). Believe me, the "one-way connectivity" problem is one of the worst problems that you can have in a LAN.
