Hong Kong to SHANGHAI routes

We have noticed there's been an increase in latency from Hong Kong to SHANGHAI. Usually running about 70-80ms, up over 300ms now. Per a traceroute I can see NTT is jumping over to LA before going over to Sha(China Unicom) via Level 3. Anyone else on this thread seen this behavior and or have any information at to why this is happening? Level3? China Unicom? NTT? Any engineers from these companies on this thread?
