Currently I am using U.S: Eastern for the installation, but there are substantial outages plus I want decrease lag for European users. Therefore I plan to add a Azure WebSite instance in Europe and also replicate the database. I read a number of articles (e.g. this one explains how to get an application ready for Azure with redundancy: http://msdn.microsoft.com/en-us/magazine/dn786914.aspx) but I am unsure if all this will work with DNN (current version).
