Reader Matt wrote to me with the following: "I had to take bl.spamcannibal.org out of my DNSbl checks due to 1+ second DNS response times and zero unique hits. Do you have any details on what's going on with them? Are they dying or dead?"
Matt, don't despair. I reached out to the publisher of the Spam Cannibal DNSBL (bl.spamcannibal.org) and he let me know that Spam Cannibal is experiencing a system issue with their primary database mirror. A new system should go online soon and then things should be up and working again.
I'll update this page with more information as I receive it. Stay tuned.
