// Note: on server failure, partition masters should be switched to the slave
+// Note: MediaWiki will fail-over to other shards when one is down. On master
+// failure, it is best to either do nothing or just disable the whole shard
+// until the master is fixed or full fail-over is done. Proper fail over
+// requires changing the slave to stop slaving the old master before updating
+// the MediaWiki config to direct traffic there.
