This link is an aerial fiber link (fiber is strung along the path of a high-voltage power line). Such links have lower reliability because storms, trees, ice, and the occasional hunter can damage them. 2/

We used to de-bugging software and hardware but de-cowing network is something new.

Cows do enjoy a high-fiber diet, so this checks out.
