Your ISP could also use their alliances with fellow ISPs to block DDoSes at their source. They do neither. I got DDOS'd over a stupid email list spat (I banned an obnoxious spammer, he picked up my email address off of past messages 'recieved from') a few years ago, it just about totally knocked my ISP's backbone connections (a couple DS3's) offline. ISP apologized but said if it happens again we can't afford to keep you as a customer. -- john r pierce, recycling bits in santa cruz
