What's very interesting to me is the very rhythmic peaks-and-valleys you show... Seems to go up every day, down during the night; gradually rising mon-wed, slight drops thurs-fri, and then big drop sat, lower drop sun, and then jumps back on monday.

We saw a dramatic decrease. Attached is our dnsbl mirror in .ie, it mirrors spamhaus amoungst other things.The numbers are in 1000s of 1000s per 5 minute window. (so 2500k = 2.5m)You can see a dramatic decrease that corresponds with them going offline and then the spam level gradually coming back, but it's certainly not back full tilt yet.Paul Paul Kelly Technical Director Blacknight Internet Solutions ltd Hosting, Colocation, Dedicated servers IP Transit Services Tel: +353 (0) 59 9183072 Lo-call: 1850 929 929 DDI: +353 (0) 59 9183091 e-mail: paul () blacknight ie web: http://www.blacknight.ie Blacknight Internet Solutions Ltd, Unit 12A,Barrowside Business Park, Sleaty Road, Graiguecullen, Carlow, Ireland Company No.: 370845 ________________________________________ From: Frank Bulk [frnkblk () iname com] Sent: 06 December 2008 03:33 To: 'Peter Serwe'; Skywing Cc: nanog () nanog org Subject: RE: McColo and SPAMWe experienced exactly no decrease with the McColo shut down a few weeks back, even though we receive 2M+ messages per day. It's interesting that each service provider's spam populations are as different as they are. Some experienced gigantic decreases, others didn't. And it's not like we havejust one domain. I know MessageLabs examines spam rates per industry type.

Do you feel the same ? Many thanks, ROIt would seem that the sources of SPAM have merely moved since McColo was shut down and it's going to take some time for everyone's blackhole routes and RBL's to catch up. I have personally noticed a higher delivered spam content in my own email accounts. Peter -- ピーター-- ピーター <aggregate-month.png>
