Servers upgraded & update size improved [link]    13. October 2006
We apologize for any downtimes over the past days. The servers for this website and the main update information has been replaced; some update mirror servers will be upgraded as well.

Also, beginning next week, the size of the weekly update files will be reduced as we're optimizing the process of downloading only changes. As a result of this, users using the advanced mode in Spybot-S&D will probably notice additional filesets; those ending in the letter C are new ones containing the most up-to-date detection rules.
