Network Investigation
A working connection is not the same as a stable route.
Reality can help with connection establishment and traffic camouflage. But peak-hour congestion, packet loss and poor outbound routing from China can still make the connection feel unstable.
VLESS Reality mainly helps the connection get established and stay less obvious.
After that, your traffic still has to travel through the local network, China’s outbound path, international transit, the overseas data center and the final service. If any part of that path is unstable, the connection may still feel slow.
Night time is often peak usage time. More users are competing for the same outbound capacity, and ordinary international routes may become congested.
This is why a setup can feel usable during the day but suddenly show ping spikes, packet loss, slow page loads or video buffering at night.
Owning the VPS does not mean owning the route.
If the path from China to that VPS is already poor, a strong server and a modern protocol may still give you unstable real-world performance.
Do not compare only protocols. Compare routes.
The protocol helps decide whether the connection can be established. The route often decides whether the connection feels stable enough to use.
Many network problems are not about whether a connection exists. They are about whether the connection remains stable after it exists.
If your main issue is gaming latency, unstable streaming or peak-hour slowdown from China to overseas services, route testing matters more than simply changing protocol names.
