• NS records removed from SURBL zone files

    June 22, 2009

    As of 22 June 2009, NS records have been removed from the SURBL zone files. This should not affect operators of either public or private DNS mirrors, since the records are not needed in either case. The main impact is that private DNS mirrors no longer need to take the extra step of removing the NS records.

SURBL Data Feed Request

SURBL Data Feeds offer higher performance for professional users through faster updates and resulting fresher data. Freshness matters since the threat behavior is often highly dynamic, so Data Feed users can expect higher detection rates and lower false negatives.

The main data set is available in different formats:

Rsync and DNS are typically used for mail filtering and RPZ for web filtering. High-volume systems and non-filter uses such as security research should use rsync.

For more information, please contact your SURBL reseller or see the references in Links.
