    Link Mauve: is your DNS okay? my server says `Server-to-server connection failed: ServFail in AAAA lookup`

  2. mjk

    for muc.linkmauve.fr to be precise

  3. Link Mauve

    mjk, I just updated the SOA, but it responds correctly here.

  4. Link Mauve

    Ah hmm, not on other resolvers…

  5. Link Mauve

    My own resolver, as well as unbound, are happy, but neither Google nor Clownflare.

  6. moparisthebest

    Is the old server not responding for that domain anymore? You'll want to keep that working a few days

  7. mjk

    yeah, caches gonna cache

  9. Link Mauve

    moparisthebest, which old server?

  10. moparisthebest

    I assumed you switched servers, otherwise what's causing the ServFail

  11. jonas’

    Link Mauve, maybe https://dnsviz.net/ has ideas

  12. Link Mauve

    It seems old and not updated since 2021. oO

  13. jonas’


  14. Link Mauve

    Its view of my zone.

  15. jonas’

    then click the update button at the top

  16. jonas’

    (search for "Update now" on the page, it's a link actually)

  17. Link Mauve

    Ah thanks, my IPv6 GLUE hadn’t been updated!

  18. jonas’

    dnsviz is hands down the best ad-hoc tool to get a comprehensive view of potential DNS issues

  19. mjk

    fwiw, I've also seen the `ServFail in A lookup`

  20. Link Mauve

    There, everything fixed, thanks!

  21. mjk


  22. Link Mauve

    I migrated my DNS server back to my main server.

  23. Link Mauve

    Now that I found the problem that caused me to do an emergency backup restore on a server of a different architecture.

  24. Link Mauve

    (It was my parents, shutting down the UPS because it made noise, which had the hdd of the server plugged in.)

  25. Link Mauve

    (So the server obviously couldn’t find its hdd any more.)

  26. jonas’

    servers tend to indeed not like that

  27. mjk

    so making noise is a vulnerability 🤔

  28. Link Mauve

    Poor UPS just wanted to tell us the battery was dead.

  29. mjk

    "don't sh{u,oo}t down the messenger"

  30. Link Mauve

    mathieui, DNS is now fixed btw, I’ll receive emails reliably now perhaps!
