For those that use files from bleedingthreats.net ( or bleedingthreats.com ) there seems to be a problem with the sites.
From The Bleeding-sigs Archives those names haven't been able to be resolved since 11/22/2007. ( a look-up indicates the domains were updated 10/21/2007 )
For now updates can apparently be found at The DNS-BH project
Anyone have more info on this ?
