I would diversify across several tld's and be ready to make use of any of them in your application by switching a properties file or database entry. Should there be a problem with a set of root servers, your SLA impact can be reduced. Even for my personal hobby sites, I always get at least 2 TLD's, sometimes 4+. That is just my own opinion based on my own experiences. There is also some factor of brand protection in this method. If you wait until your business is successful and fast growing, it is too late to go back and get all the TLD's for your brand. They will have been snatched up and you will have been too busy to remember this or notice until it is too late.
