can you provide traceroutes to the address?

@andrew | as1003 yes, this was the traceroute when it had packet loss, I can't reproduce it all the time, but most of the time these days I got packet loss

sorry can you send an mtr too

shellflyOP•2w ago

this was what I got last night when it had packet loss, I can't reproduce it right now, I'll provide mtr next time the issue happens

andrew_nyr•2w ago

It * may * be due to congestion in your isps network based on time of day but an mtr should show that

That looks like you're connecting out from China / China Unicom. Packet loss is pretty par for the course for outbound connections from China/across the gfw. Cloudflare offers their own China Network which requires Enterprise and an ICP License

I have used Cloudflare CDN for a few months now, but I only have this issue these recent days, so I wonder if there is any change on the CF side or any settings I can adjust does this mean there is no guarantee of stability for China Network without Enterprise license?

Chaika•2w ago

Cloudflare locations in China/Cloudflare's China Network addon is only on Enterprise and requires an ICP License: https://developers.cloudflare.com/china-network/ Without it it, you connect only to locations outside of the China Network/pass through the gfw and such, usually hitting US west coast cloudflare locations. and of course going through that means all the usual packet loss/instability
