Same as I do for my web hosting company's name servers. I have them actually running at multiple locations so that it keeps my clients unaffected if there was an issue on one network. This way, I do not have to worry about one being down. I also do RAID 1 on my boxes as well as a side note in case of hardware issues.

My point being, if you are mission critical, invest in the redundancy options.
