Some wanker has hacked the frontpage of bt.etree.org. All of the data is safe and sound. It appears that ibiblio.org's webserver has been compromised. However, you can still access the site through the RSS feed:
» http://bt.etree.org/index.xml
And browse by artist is still working:
» http://bt.etree.org/browse.php
Update (20:58): everything is working fine again!
