Caution: Buried Wires

A few days ago I finally picked up the phone and ordered FiOS. Two things happened yesterday: (1). someone got into our fence and laid down a FO cable; (2). my Comcast cable TV and internet died. Although suspecting the above two might be somehow related, I called Comcast to arrange someone coming to look at it. 5 pm today a truck pulled in my driveway and came the cable guy. After brief connection checking he asked, "When did the problem first start?",
"Yesterday when I got home", I said.
"Did someone dig in the backyard?"
"Very likely, Verizon just put in some fiber optic cables."
"That must be it! They broke the cable." and he added, "I have seen this happened a few times".
He decided to pull a new line from the utility box. For some reason the box was stuck tight but our brave cable guy kicked it open anyway. Wires were exposed. With me holding my flashlight, he went through those Medusa's hairs, but failed to find any labeled as mine. He went ahead disconnected a non-labeled one (I expressed some ?? but he said that was just an extra hot connection), and luckily no angry man came out yelling at us for interrupting his entertainment. The cable guy put the newly cable on. Voila, I'm online again! Now, since the new cable has to be buried, I wonder if Comcast will manage to cut Verizon's fiber optic cable as well...

Anyway, I'll soon be enjoying my 15Mb/2Mb FiOS, I hope.
