Sword of the New World servers went down for a scheduled maintenance and hardware upgrade on 27th May 2009 at about 2.30pm (PST). The forum was also down. Attempts to access it yield "IPS Driver Error. There appears to be an error with the database."
The maintenance was supposed to be for 24 hours. Instead, it has been more than 4 days and still counting... Here is a Dilbert comic strip that should reflect what seems to be happening with K2. (Thanks to Almontri, who thinks that liking pie is a big important announcement, for the comic reference.)

Update: SNW went online on 1 June 2009 at about 8am (PST), bringing the maintenance period to 4 days 17 hours. The forum is still down at the moment. In future, see SotNW Twitter and K2-Guinn Twitter for news, especially when forum is down as well.
