The 2026-10-19 reboot left every franksdank.cloud name NXDOMAIN for LAN clients while external names kept answering from cache; the file was mounted and readable and dns.hosts was intact, and 'pihole restartdns reload' restored every name in seconds. Mechanism not established. Instrument and remedy now on the owner page, plus a failure-mode row for the FTL rate-limit case seen beside it (10.0.2.x = a pasta container's forwarder).
