Database issue fixed, if you can't login to silkroad, keep closing it and re-opening it, and it will update your client [eventually].
Rev6 server issue was caused by table from the database being moved from ram to harddrive for commit and using 100% of the harddrive speed, causing entire website to slow down. This error was occuring for the past 36 hours on rev6, it is now fully fixed. We will also upgrade the harddrive in the next week or so to prevent such a thing to happen in the future.
