  • nsec3-guidance is going to be a BCP RFC soon
  • nsec3-guidance affects both zone publishers (authoritative DNS side) and DNSSEC validator operators (full resolver side), but timing of when they will follow nsec3-guidance may differ
  • Due to the timing difference, possibility of name resolution failure of TLDs (large outages) is highly concerned
  • Explain possibility of the large outages at TLDs and propose some mitigations
  • Aiming smooth deployment of nsec3-guidance
