I believe Arecibo was destroyed by a hurricane, possibly by Maria. Photos look really bad. My son living in PR said the year after Maria, PR was like a third world country, and as a small construction company he had his best year ever. A lot of mainlanders have vacation/investment property/condos in PR which need reliable service in their absence. He also did a lot of work helping his wife’s family with post storm problems.
Arecibo was damaged by hurricane Maria in 2017, but was much more damaged in 2020 by the structural failure of the receiver structure suspended over the dish. This whole thing collapsed into the dish. It seemed totalled.
