shade The drop might not be damaged but a couple things could be wrong:
Line techs sometimes disconnect people at the pole, happened to my friend. I don't know why techs do that but they should get in trouble for it. Perhaps if a split has too many users on it?
Moisture in the splitter or the drop coupling.
Of course, the ONT could be sunk too, or the power supply.
Or a problem at the CO or even the company disabled accidentally.
So many preventable causes that are common.
