The Luminous Landscape suffered a major server crash yesterday (Thursday) afternoon, resulting in the site's longest downtime in 11 years. Michael tells me the situation is under control and they're in the process of reloading the site from a backup. They hope to be back online as early as this morning. So if you've tried to log in and had problems, don't worry—all should be well before long.
Good luck to L-L, and we'll keep you posted of any further developments.
UPDATE: ...And they're back. After about 24 hours down, L-L is back online, and "It appears that there was no data loss." Good news.
