I wonder if it's the same Chinese source as the attack on DNSMadeEasy in November and December? It was a multiple-gigabit, sustained attack on hundreds of thousands of domains. 4 of my domains were part of it, and I had to move them to another DNS provider to avoid going over my 10 million monthly queries limit.

I didn't really hear anything about it except from another DME customer that posted on HN. DME never even informed anyone about the attack.
