It is a test server so changes and fixes are being made to the hardware and software on a rate that is more frequent then then production servers. Also, there is no backup hardware so the only machines available are the ones being changed.
When this moves into production, there will be multiple machines. At that time, most changes will be done by taking down only one machine at a time. Since all services will be available from other servers, users should not see an impact other then possibly speed. There are likely to be some changes that may require all of the machines to be turned off to make some changes. However, the service should be almost always available.
