if RF=2 and min.insync.replicas=1 (the default) then you shouldn't have offline partitions if 1 of 3 brokers is down.
I'd first double check your topic config (and broker defaults) for the one that went offline to verify RF/Min. Be sure to check each partition they can be different! ( kafka-topics.sh --zookeeper <zk_string> --describe --topic <topic_name> ). IF they are good, maybe one of the remaining two brokers had an issue at the same time? Check out the broker logs?
