Nothing, just normal F5. 
Taobao got a very constant event to grab stuff at 1AM, if that time got lag, very easy to spot on.
Normally it take offset -0.5s, which means reload at 00.59.59.5s, get the button loaded and submit before 01.00.01s
After the undersea fiber cut off, it become 59.3s.
This month, 59.0s
Today midnight, 57.0-59.0s
Now 9 AM, 59.0-59.5s.
Because at 1 AM, normally QoS have return normal, so it is also one of good timing for testing network.
So during that time, if high latency and little bit jitter, means just starting getting bad.
If high latency with high jitter, means start packet dropping, it can be MY to HK, or HK to Mainland.
The worst?
Whole API hang, until you reload, caused by HK to Mainland hang, old bug since 10 years ago, can be facing on any website.
If F5 fixed it, means CDN server to main server, if F5 will hang, means MY to CDN server.
When this issues return normal, then undersea fiber fixed, the old worst is QQ disconnect and fail to sync message, but Tencent have Asian server running now, so can't test already, what's left the the QQ chat pic that still hosting on HK.
Anyways, the best timing to test UniFi QoS is during 10 AM - 12 PM and 7 PM - 1 AM.
If QoS kick in on morning, then it means undersea fiber hurt very bad.
If QoS kick in on night, then it means still acceptable, like now, always kick in during 7 PM.

So far Lazada App also affected, but it seem like it is server side issues + App design, not MY to SG connection issues, because the lag happen when the homepage module failed to obtain from server, but not when it is working fine.
if you can ask TM provide you CN2 would be the best. Taobao got a very constant event to grab stuff at 1AM, if that time got lag, very easy to spot on.
