datacenterknowledge.com seems to be having some issues right now (the HN effect? ;) Here is the gist of the post:

     The social bookmarking service Ma.gnolia reports that 
     all of its user data was irretrievably lost in the 
     Jan. 30 database crash that knocked the service 
     offline. That means that users who were unable to 
     recover their bookmarks through publicly available 
     tools (including other social media sites and the 
     Google cache) have lost all their data.



     Ma.gnolia founder Larry Halff said last week that the 
     service’s MySQL database included nearly half a 
     terabyte of data. Yesterday Halff informed users that 
     a specialist had been unable to recover any data from 
     the corrupted hard drive. ”Unfortunately, database 
     file recovery has been unsuccessful and I won’t be 
     able to recover members’ bookmarks from the Ma.gnolia 
     database,” he wrote.
