Just had to go through a software upgrade on the server, sorry for the disruption on the weblog and the café this past half hour or so.
Couple of days ago, I had to restore a weblog backup, because the wordpress vm had gone into some infinite loop three times in the past month. Had to fix a problem with debian gpg keys (and found out that one of my two backup mechanisms wasn't correct - great test, but a bit frustrating at that point in time of course).
Everything should be running smoothly again now. The VMs had been running for 6 weeks without a hitch.
Btw, I still need to find a replacement for this bbPress forum, it's the last step before I can cancel the rented server. Am considering Drupal for this. Takes a bit of configuration, but looks like it's very flexible (and evolving further at a fast pace, unlike bbPress).
