dnsbl.proxybl.org offline?

This morning I got a bunch of calls about all of our websites/portals taking 20+ seconds to load a page.  I jumped on our web server and it was running fine so I logged into the UTM and opened the WAF live log and saw a ton of these for every page request:

DNS lookup for 83.16.168.192.dnsbl.proxybl.org. failed

This the the dns reputation lookup that we current have turned on.  It appears that proxybl.org has had it's DNS wiped out!

I have temporarily turned off the reputation lookup and things are again running normal.  Just thought I would share in case anyone else is experiencing this.

  • Yes they are down.  You have to turn off reputation checking to eliminate the error currently -- I had this affect website access performance at one customer site already due to this issue.  You can't granularly turn off that one RBL -- the UTM uses 3 of them for this feature currently.  I've started a support case already with Sophos to find out how to turn out the one RBL that's dead.
