We're having some customers reporting problems emailing business 
partners in China. We've done some checking, and we're getting timeouts 
to certain nameservers in China, such as ns1.qq.com. When we mtr to one 
of these, we see high latency and packet loss at 
CHINA-TELEC.edge1.SanJose3.Level3.net.
