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.
