Backhoes surround AT&T office in Arlington VA

The AT&T toll office in Arlington VA is surrounded by a half-dozen backhoes (2 in front, more in the side-street around the corner). Instead of the usual "call before you dig" markings, they had full crew of professional surveyors marking a grid and repair trucks from multiple telco/carriers standing by. A lot of "suit & tie" folks on-site too. Probability before I lose some service? https://www[.]donelan[.]com/pictures/
