tldr; single bit flips in a hop to a remote server.
the moral of this story is - the number of layers and abstractions between our code (even our shell scripts - cron jobs in this case) and the network layer is so large.. the most subtle of bugs in one of these layers is a massive pain to track down.
i am in awe of the tenacity of these bug hunters.
