I get a call from a large medical office that I support complaining that their internet is down. Take a look remotely and confirm that they are dark, hop in my van and head 15 minutes down the road. I fly into the parking lot and immediately notice a boring machine sitting in the bar ditch. I walk out, look at the little flags, one row of which had been planted by our ISP.
I look left, there's the boring machine. I look right there's a pile of dirt. I look at the flags marking a straight line betwixt the two. Wander on down to the workers.
"Hey, I think you guys might have bored through our cable connection."
Worker 1 looks at the flags and the machine and the dirt pile, looks back at me and says, "you're probably right."
Worker 2 waddles up and asks what's going on. I repeat myself. "Nah. Couldn't have been us."
Oh, I'm sorry - it must have been a MUTANT GOPHER FROM THE NUCLEAR BOMB PLANT 20 MILES AWAY, huh?
After another one of those incidents, they finally decided to spend $35 a month on a backup internet connection (Internet Insurance is what I call it.)
