Real Network Case #001
A player using a university dormitory network in Italy had 220–280ms latency and unstable gameplay throughout the day when playing China server League of Legends.
Haipaida judged that the main issue was not simply the VPN or acceleration node, but a bottleneck inside the campus network before the traffic reached the wider internet.
The player was staying in an Italy university dormitory and wanted to play China server League of Legends with friends in China.
Basic internet access appeared usable for normal browsing, messaging, and video. However, once the player entered LoL CN, latency stayed around 220–280ms and the connection remained unstable throughout the day, not only during evening peak hours.
This was not a typical case of simple long-distance cross-border latency. The local network environment already appeared to be creating a bottleneck before the traffic properly left the university network.
Before the connection reached the wider public internet, it had already passed through multiple layers inside the campus network.
The most important sign was that traffic passed through 9 internal network hops before reaching the public internet.
This means the issue was not only “Italy is far from China” or “the acceleration node is not good enough.” In this situation, the local campus network could already introduce latency, jitter, and instability before any cross-border route optimization could help.
The main bottleneck in this case was inside the campus network.
Haipaida did not recommend directly purchasing route optimization for this case. Even if the later cross-border path improved, the front-side campus network bottleneck could still prevent the overall gaming experience from becoming stable.
The first priority was not buying another accelerator, but changing the network environment first.
If possible, the player should test a network outside the dormitory, such as a fixed broadband connection elsewhere, a friend's home network, or another cleaner internet exit.
4G/5G mobile data can also be tested as an alternative, but mobile networks come with their own risks: weather, signal strength, base station load, and indoor coverage can all cause packet loss, jitter, or sudden ping spikes.
For campus network bottleneck cases like this, route optimization is not the first solution. It only makes sense to optimize the cross-border path after the local internet exit is reasonably clean.
High latency when playing China server games from overseas is not always caused by a bad accelerator.
Some problems happen on the cross-border route. Some happen at the ISP routing level. Others happen much earlier, inside a school network, dormitory network, apartment network, or shared Wi-Fi environment.
If the real bottleneck is local, blindly switching nodes or buying another route may have limited effect. Finding where the bottleneck is matters more than buying first.
