China’s Great Firewall and cross‑border Internet can seriously hurt site availability. We ran tests from remote desktops inside mainland China to compare three setups:
Latency: 300 ms up to tens of seconds
Packet Loss: 40–60% TCP loss
Result: 🔴 Congested, unpredictable routes
Fig. 1: "Directly from US" setup
Ping Latency: ~100 ms
HTTP Latency: Still high and uneven
Packet Loss: ~40% TCP loss
Result: 🟡 More predictable CN2 backbone for TCP, but HTTP stays unreliable
Fig. 2: "From Honkong" setup
Latency: Stable, low for both HTTP and TCP
Packet Loss: 0%
Result: 🟢 All traffic stays inside China. No Great Firewall delays
Fig. 3: "From inside China" setup
Only hosting your site fully in mainland China delivers loss‑free, low‑latency access for Chinese users. And this is what we can provide with the Digital Experience Mesh.
