It looks like the database can not be recovered from the old hard disks - both disks in the RAID1 array are totally broken. Because we absolutely do not want to lose removal requests, we will not restart the list from an older backup. If the list gets continued (interest has been expressed by several organizations), it will start with an empty database.
This is unfortunate, since we recommended DSBL as an excellent compliment to our other recommended lists. Due to its current status, we have removed "list.dsbl.org" from our default configuration. Should DSBL return, we will use it again, but most never do.
