Today XIVDB's Character tracking database hit capacity (80GB) on it's storage node.
As XIVDB continously pulls information from the character tracking server it caused a build up of out of sync data and in attempt to stop the database a few tables became corrupt and the database would not restart.
To repair, it means re-importing the entire database from backup and due to it's size this takes a very long time.
I am hopefull it will be back online by Midnight UTC
I am extremely sorry.
