Colo BKK very slow

Hi,

Since a week or so, I noticed the images download from our sites is very slow. Upon investigating I see that when using the PoP BKK it’s slow.

Our cloud servers are in singapore. When directly accessing assets, it is very fast.
for example here is a direct link to our assets:

https://assets.sg-sin1.upcloudobjects.com/test/foodtruck.jpg?v1
Total time: 0.742312

the same asset but then behind Cloudflare proxy when in Thailand BKK (PoP/colo=BKK):

https://assets.deevelop.com/bstatic/foodtruck.jpg?v123
Total time: 10.958349

the same url but then connected via vpn to malaysia (PoP/colo=SIN)

https://assets.deevelop.com/bstatic/foodtruck.jpg?v124
Total time: 0.9231832

Connection time and TTFB were in all cases very low. Only download time is slow.

So it’s weird, looks like the Cloudflare routing makes downloading 10x slower. The status page says it’s operational.

Is there anything I can do? Lazy to migrate to another service, but this is killing for our users.
