Noticed this posting on the official LOTRO forums this afternoon:

All Turbine services - games, websites, and forums - will be down for maintenance on Monday, November 26th from 6:00AM - 12:00PM EDT. Thanks for your patience during the maintenance!

Update to the Update: We are having to extend the window to 6pm EST due to technical issues effecting all of our products. We apologize for any inconvenience this may cause, and we are working as hard as we can to get things back up and running.

I have to go back to work anyway!
