Hi,
Assume that:
1) You're a user of BitFolk's secondary DNS service.
2) One or more of your zones have been unreachable from our
secondary servers for so long that they have expired.
How long would you expect BitFolk to continue serving SERVFAIL for
your zone(s) before removing them from the configuration (and
thereafter serving NOERROR/REFUSED as for any name they're not
authoritative for)?
If this happens would the owner automatically get a ticket?
Can you tell from whois or elsewhere whether you're still listed as an
auth server?
If any of you use other similar services where you
provide the
primary DNS server, what do they do in that circumstance?
Is there a difference in behaviour in typical Internet protocols
that encounter SERVFAIL vs NOERROR? e.g. would a mail server
consider SERVFAIL to be a temporary failure but NOERROR to be a
permanent one?
These are things I don't know and haven't really thought much about. :-(
It'd be an interesting thing to know tho'...
Regards,
@ndy
