Yesterday at 11:00 CET we experienced fault on one of our database nodes. Faulty node was not removed from cluster and caused slow down of all queries. Because of such slow down majority of our input
nodes was not able to get enought information about mail accounts existing in our infrastructure, this resulted in rapid growth of deferred messages. Messages were deferred both in our infrastructure and on clients endpoints.
At 11:47 CET we manage to bring our database cluster to normall state. Unfortunately we were unable to instantly deliver all deferred e-mail messages. At 12:06 CET growth of mail queues was stopped. At 13:57 CET last
queued message was delivered.
