We have two fibre optic cables linking up two of our buildings. works great

Well we got the cables replaced today. Guy traced the cables, pulled them out from underground and back to the cabinet. Cuts the 3 cables, right time to terminate the new cable...

 

Hang on, wait a minute... Why has 3 of the lights on the core switch just gone out? Oh feck!...

 

He'd managed to cut 3 of the fibres which form the backbone of our network, taking half the school down.
