Ooghf.

You are right. The OP simply said "a config file", and we've all assumed.

Hopefully Lewis knows / understand that we are just squabbling amongst
ourselves because we've know each other for a long time and this is in
good humor.

Assuming that it *is* an SOA (which is a reasonable assumption at this
point :0) ) yes, that is 15 seconds, and is almost definitely not what
you want.

RIPE has a suggestion (
https://www.ripe.net/publications/docs/ripe-203 ), SWITCH.CH has some
others (https://securityblog.switch.ch/2014/02/06/zone-file-recommendations/)
, Peter Koch (related to the RIPE page :-)) had others:
https://tools.ietf.org/html/draft-koch-dns-soa-values-01

The actual values used are open to tuning, but in the original
posting, you, that was 15 seconds, and was *probably* a typo for 15
minutes. I personally always use seconds in my zonefiles, and avoid
the new fangled hours / weeks / syntax.

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
