Glad you're okay, Doc!
We had a similar experience last year, but not nearly as scary. The phone company marked out where their lines were, and then we had a guy come in with a backhoe. He cut a phone line and took out about 100 people's phone service. The phone company was just careless. We told the backhoe guy that we'd go to court with him to testify if he needed it, but the phone company admitted their error. I was chatting with one of the phone guys, and he said if someone cuts a fiber optic line when it's been properly marked, it can cost them up to $40,000. I guess they are required to have an ambulance crew on hand when they splice those optic lines.
Anyway, glad things are okay!
