A full-zone write died with SSL UNEXPECTED_EOF_WHILE_READING. Not our request: three plain requests to their API from one machine gave 000, 200, 000 within a few seconds. Their endpoint is simply unreliable, and the operator was being made the retry loop. Only a connection that produced no response is retried. An HTTP status is an answer, however unwelcome, and repeating a request the server already judged turns one refusal into several. Retrying a POST is safe here specifically because set_hosts replaces the whole zone with add_dns_to_current_setting false, so the same body applied twice leaves the same zone and a reply lost on the way back costs a duplicate write and nothing else. The comment says plainly that this does not transfer to an endpoint that appends, and a test pins both halves of that reasoning.
