Hi Len, you hit return just before me, so I simply add few things to your message. The Mixmaster flood we saw in the last two weeks is unprecedented, as volume of mail that flow *successfully* throught the remailer. Most trafficked ones remailers a tenfold raise of their normal traffic for days; George peaked as 60K message a day. The only (strange) measure I took was stopping nilsimsa, that was completely uneffective against the flood but was responsible of a too hight load on cpu. Done this, also considering that most of remailer now had better connectivity than a couple of years ago, I was surprised how well a lot of remailer survived against this flood. I'm surprised (negatively) of the lack of any public reaction of remops community, that didn't share any info to better react to the flood, and didn't react at all as "community" . Another thing. I wrote a mail in the Mixminion list because I suspect that a different Dos was attempted against the mixminion network. No correlation seems to exist between software version and surviving nodes. Now more that 60% of nodes are down, but once more no reaction at all comes from the operators. I'm positively concerned for this lack of reactions and mutual help from both community. Any opinion ?
