Well, to make a long story short, the /home directory was encrypted as it was supposed to primarily contain personal data & inboxes when the server was setup. Both encryption key copies were lost due to HW failure, and no, it was dd'ed from /dev/random, so no chance of brute forcing it. /home had no backups as it was (1) too big (see below on new HDD) and (2) was presumed sufficiently redundant (RAID 1+1+1, 2 keys). Additionally, when we moved from Subversion to Gitolite, the data that used to be in /vcs or /var ended up in /home. Hence also the Gitolite-managed Git repos were lost (note that the research data we still kept in /vcs is unaffected, as that was the location for non-private data by design...). Finally, while the Drupal site database is fine, /home included all uploads and the Drupal configuration, so old.gnunet.org is also down until someone finds the time and energy to restore it. Irnoy: The 8 TB replacement HDD for moving the data to a 2nd new server in Bern (as I was quite uncomfortable with managing an 5 year old server remotely with no physical access from the team for many years) had been ordered a few days earlier and arrived _literally_ a few hours too late to help. Anyway, the Bern site has right now IPv6 trouble, but once that has been sorted out and the sysadmins have made progress, we should have _two_ sites with copies of all of the important data. Oh, and thanks to Andreas we're this time having three copies of the encryption key used on the partially restored gnunet.org host.
