If everything goes wrong, can you fix/diagnose a Solaris box quicker than a FreeBSD box? If to you the costs of maintaining each OS is equal, then why not use both? If you anycast your deployment of DNS servers it is easy enough to light up and extinguish differing resolvers when they develop faults: http://www.digriz.org.uk/ha-ospf-anycast - Linux/Cisco but adaptable There is actually some weight and sensibility to have a variety of OS's to provision a service (and by extension a mix of DNS software). For example, say a vulnerability is found in one of the two OS's you use, only one of your resolvers is exploitable. Sorry for the non-answer, but 'both' is also in my opinion a good suggestion :) Cheers -- Alexander Clouter .sigmonster says: Age and treachery will always overcome youth and skill.
