Any service that wants to use memcache for the keystone authtoken caching should be configured with a single server for optimal performance when server might be unavailable. This is due to the way most python memcache libraries operate. Most put the memcache servers into a pool and if one goes down, the request will incur a connection penalty if the server is unreachable.
