DNS nameserver failover was fixed in 2022 by #8847, which changed `DNSHandler::mainEvent` from response-driven one-shot scheduling to a periodic timer (`schedule_every`), so a dead primary is now detected and failed over even when it never responds (the chicken-and-egg the report described). A gold test (`dns_down_nameserver.test.py`) covers the down-then-recover case. The fix first shipped in the 9.2.0 release and is in the current 10.1.2 release. Closing as fixed. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
