Along these lines, one of the obvious things missed in this post: monitoring. Setting up DNS servers on low cost VPS providers has some inherenet risks as they tend to attract all kinds of abuse, which can lead to things like mass scale UDP filtering to keep operations online. When I scaled down my colo footprint I started to move DNS operations to various VPS providers to maintain redundancy, but kept my monitoring in place to perform health checks at 60 second intervals. Finally got annoyed enough with all of the filtering events tripping monitoring that I migrated everything to a hosted DNS provider.
