I would like to check if anyone here know what the company MasterTec does. For the last month or so, they have been in my neighborhood digging and working on a control box. What I mean by control box, it is a metal case that is about chest high. Only thing I see on the side of the tents. It just says "MasterTec fiberoptics"
