Another case is if memcached crashes or must be restarted (for example
due to some critical bugfix). Sometimes it is very painful to restart
one instance with few GBs of cached data, it is better to have a
couple if instances with less data that can be restarted one at a
time. But this depends on what is cached and how painful it is when
the cache is lost.
