In March 2009 we stopped delegating public DNS service of individual
list zones such as sc.surbl.org, ws.surbl.org, etc., since they are
obsolete and all their data are included in multi.surbl.org. We would
also like to stop rsync service for these files, again since their
content is included in multi.surbl.org, which is the only zone anyone
should be using. If anyone has feedback about this proposed change,
then please contact us by email at rsync at our domain.
We've added a couple more malware data sources to the PH list:

6/27/09: As of 27 June 2009, the PH list includes ZeuS Tracker malware
host data.

10/18/09: As of 18 October 2009, data from Malware Domain List has
been added to the ph list.

Most of the data sources on the PH list are filtered to exclude
significant sites that are cracked or abused. This is to reduce
potential false positives on sites that are abused, but may be
mentioned in significant volumes of hams.
