Spamhaus has mostly mitigated the dDOS against the Spamhaus website and mailserver, but now the CBL is under attack. They have been working to get that under protection as well, but it’s taking some time.
Right now there are no public channels for delisting from the CBL. The Spamhaus Blog will be updated as things change, and I’ll try and keep things updated here as well.
UPDATE: Cloudflare talks about the scope of the attack
I got mail late last night from one of the Spamhaus peeps telling me that they were under a distributed Denial of Service (dDOS) attack. This is affecting email. Incoming email is delayed and they’re having difficulty sending outgoing email. This is affecting their responses to delisting queries.
They are working on mitigation and hopefully will be fully up and running soon.
Updates when I get them.
Update (8/29/2012): mail to Spamhaus should be back.
Today’s been chock full of phone calls and dealing with clients, but I did happen to notice a bunch of people having small herds of cows because Spamhaus listed www.gmail.com on the SBL.
“SPAMHAUS BLOCKS GOOGLE!!!” the headlines scream.
My own opinion is that Google doesn’t do enough to police their network and their users, and that a SBL listing isn’t exactly a false positive or Spamhaus overreaching. In this case, though, the headlines and the original article didn’t actually get the story right.
Spamhaus blocked a range of IP addresses that are owned by Google that included the IP for www.gmail.com. This range of IP addresses did not include the gmail outgoing mailservers.
Spamhaus says
A colleague was asking about confirming transactional mail today. It seems a couple of big retailers got SBLed today for sending receipts to spamtraps. I talked a few weeks ago about why it’s important to let people unsubscribe from transactional email, and many of those same things apply to confirming receipts.
