Normally whenever I see a 503, that means the Solr Cloud has one of its shards down, i.e. there isn't a full collection available. You can see them at index time if you have lost connection to zookeeper but searches should be ok. If you see them on searches, it (in my experience) means the collection doesn't have all the necessary servers up.
