Still sticking with Linode. This is definitely not their fault. If anything I blame ISPs for letting it happen. ISP's could just simply filter traffic by filtering forged packets, then dropping traffic at a backbone would be trivial, making most botnets obsolete. AWS and Google have resources in place for their own benefit, and hosting with them means you get these benefits to some degree. But the issue is that this complicated infrastructure is only reachable by giants(amazon, google, rackspace, etc). AWS probably spends enough money, collectively, on DDoS mitigation and fallback that it could acquire another hosting company for that sum of money. The to consider the shady practices of who ever is trying to sabotage Linode's business, the likely goal is to direct business elsewhere. So you may end up moving to a hosting company who is shady enough to have caused you a loss of profits for their own profits. Somethings up here, and I'm really curious to find out who did this. I'm not leaving a business because they were a victim of espionage.
