If multiple servers provide the data, it should not matter which server
provides it. But it must made sure that only servers are taken to
deliver the data which have their data updated. It is a pretty complex
process to keep the data consistent on all servers.
If the connection is only to a single server and this single server
fails, the client does not get any data any more. If the connection is
to multiple servers and at least one of the servers is still up and
running, the client still has a chance to get its data.
