While the concern about the link to the outside world is an issue, the same concern holds for whatever provides your connectivity. As a matter of practice, when designing for availability you want to focus on the least reliable layers in a stack before focusing on other layers, otherwise your availability improvements are potentially nil.
If you can run a more reliable recursive server than your provider (or google or whoever) then by all means, however there are probably more meaningful places to spend your resources if you have a small company. On the other hand, if there is a functional reason for running your own recursive server that is entirely different, for example filtering via DNS, split view zones etc. -- Glen Wiley KK4SFV Sr. Engineer The Hive, Verisign, Inc.
