Description Björn Jacke 2014-02-22 14:13:45 UTC
the default minttl in our SOA record is set to 0, which effectively disables negative caching of DNS entries (see rfc2308). I would propose a value of 600. Default in Windows DNS is even 3600 though.

This patch should apply to 4.0 and 4.1 as far as I can see.

Once this is reviewed and in master, should be good to go.

closing this as it's fixed since months - at least in master.
