“Every time it rained, the rain collected on its leaves and branches and weighed them down.”
A line-of-sight Wi-Fi bridge ran fine for almost 10 years, then started dropping 98% of packets. The culprit was a neighbor’s tree that had grown just tall enough to poke into the beam. Rain bent the branches out of the way, and the link died about 15 minutes after the rain stopped. Turning it off and on again fixed nothing. Climbing two stories of scaffolding with no harness did.
