Ships are being routed around the Cape, but that adds 12 days. And expensive stuff is being air-freighted. I don't think air cargo has slowed in COVID, only passenger planes.

Apparently each day of a ship that can't parallel park means is will take 2 days to sort the traffic jam. Years ago it was said the large ships were followed by a dredger. I believe they sorted that since. But ships have got bigger too!
