What process are you going to use to build new hosts to ensure consistency? 3. How are you going to roll out new applications? 4. How are you going to test new apps before you roll them out to to all hosts?

You might be able to setup a local mirrored AFS server that makes asynchronous writes back to the master AFS server at the data center. > What is the rest of the groups feeling about running services like > file-sharing and email across somewhat unreliable networks and how did > you get around these problems? If you solve the larger problem(file sharing) then the smaller problem (email) takes care of itself. You can just store the mail data using the same file server and present it to the local users via a local IMAP server.
