Massive Chinese DDoS knocks out DNS provider DNSMadeEasy

Last night we noticed failed lookups on one of our domains which is surprising because our dns provider is extremely reliable. Most of the night lookups have been shaky. Turns out it's a massive DDoS coming from China and taking out core routers at Tier 1 providers including Level3, GlobalCrossing, Tinet, Tata, and Deutsche Telekom. Our DNS provider is seeing flooding of over 50 Gbps. Providers Twitter account: http://twitter.com/dnsmadeeasy Details from the support ticket: There has been a massive DDOS attack against all of our systems starting about 6:00 AM EST. Our networking team was immediately notified and have been working on resolution to the problem. Our full administrative team, as well as any available off duty technicians are being called in to assist with the situation and we hope to have it resolved ASAP. Unfortunately, our normal techniques used to fight this attack did not work properly. The bandwidth associated with this attack was able to bring down the Tier 1 provider core routers. The estimated size of the this attack is over 50Gbps and due to the nature and the negative affect it had on some of our Tier1 provider's backbones, we were unable to reroute traffic and contain the issue. We are currently working on a resolution to this attack and getting everything back up as soon as possible. This is the first time the DNS Made Easy name servers have been unable to answer queries in over 9 years of business. We will be evaluating the situation and determining what needs to occur to prevent this from happening in the future. As more information becomes available, we will be informing our client base though email and updates on our website. --- I'd like to add that DNSMadeEasy provides awesome service and obviously this isn't something they could have avoided.
