The downtime was to overhaul the billing system and other back-end projects.
LotRO CM Sapience posted this update at 4:20 p.m. EST:
"We are working to resolve ongoing issues with our system maintenance. At this time we do not have a specific estimate for when the game servers will be available. Our goal is to make the games available as soon as possible. However we would like to advise players that the service may continue to be unavailable this evening. We will continue to provide updates as we have them.
"As a thank you for your understanding and patience during this downtime, all Premium and VIP players who have logged into their account in the past 30 days (as of 6:00 a.m. EST on 2/14/2013) will receive 250 Turbine points. In addition, all VIP players who have logged in during the same period will have their accounts credited one day of VIP time for each day of downtime, plus one additional day. All points and additional time will be granted automatically as soon as our regular service is restored and stable."
