Maybe the sky is only falling a little bit
02April
There was quite a bit of breathless reporting last week about the DoS against Spamhaus and how it was large enough to break the Internet. As the postmortem has gone on, a few things are becoming clear. There was a lot of traffic, enough to swamp some major transit points. Most people, particularly in the US, saw no problems. Network engineers had more than a few sleepless nights trying to route...

Post-mortem on the Spamhaus DOS
29March
There’s been a ton of press over the last week on the denial of service attack on Spamhaus. A lot of it has been overly excited and exaggerated, probably in an effort to generate clicks and ad revenue at the relevant websites. But we’re starting to see the security and network experts talk about the attack, it’s effects and what it tells us about future attacks. I posted an...

Internet Storm Center on the Spamhaus DOS
28March
The Internet Storm Center (ISC) has a blog post up discussing the DOS attack against Spamhaus. They do confirm they saw traffic approaching 300Gbps against Spamhaus. They also point out that most people probably never knew. The attack was significant, but not globally so despite the media reports to the contrary. When news of the attack reached the Internet Storm Center, we did have a brief...

More on the attack against Spamhaus and how you can help

While much of the attack against Spamhaus has been mitigated and their services and websites are currently up, the attack is still ongoing. This is the biggest denial of service attack in history, with as much as 300 gigabits per second hitting Spamhaus servers and their upstream links. This traffic is so massive, that it’s actually affecting the Internet and web surfers in some parts of...

Some content is just bad; but it doesn't have to be
26March
There are a few segments in the marketing industry that seem to acquire senders with bad mailing practices. Nutraceuticals, male performance enhancing drugs, short term or payday loans and gambling have a lot of senders that treat permission as optional. The content and the industry themselves have garnered a bad reputation. This makes these industries extremely difficult for mailers who actually...

While M3AAWG is not directly nor officially a standards body, most of the documents have been written by members and reflect the best current practices for that document.

Spamhaus answers questions
21March
Lost in all of the DOS attack news this week is that the first installment of Spamhaus answering questions from marketers in Ken Magill’s newsletter. It’s well worth a read for anyone who is interested in hearing directly from Spamhaus. One quote stood out for me, and it really sums up how I try to work with clients and their email programs. Playing evasion games to avoid traps is...

CBL website and email back on line
20March
The CBL website is back on line. It’s possible that your local DNS resolver has old values for it cached. If so, and if you can’t flush your local DNS cache, and you really can’t wait until DNS has been updated then you may be able to put a temporary entry in your hosts file to point to cbl.abuseat.org. You can get the IP address you need to add by querying the nameserver at ns...
