I’m located in Vietnam, as the time checking both Hanoi, Vietnam - (HAN) and Ho Chi Minh City, Vietnam - (SGN) are in “Operational” state.
I’m having Pro account with Argo enabled.
Why I don’t get content served from Vietnam server?
BTW, just by manual checking, I see cache miss quite often:
1. x-cache: MISS
2. x-cache-hits: 0
3. x-served-by: cache-sin18034-SIN
