Guild Wars: Event Update

From the official website:

"The start of the Nightfall World Preview Event will be delayed by a few hours. We've discovered a corruption in the archives, and we're pulling a full backup, after which we will then examine the error, make a correction, and the event will be on its way. At this point, we anticipate that the event will not start before 5:00 a.m. PDT (Noon GMT). We will update as soon as we have further information. Thank you for your patience and understanding."
