This article addresses the common issues teams face when multiple people use a VPN/circumvention tool at the same time, such as “high node latency, inconsistent speed, and some members being able to connect while others cannot.” It focuses on how to optimize node latency, and how account environment, device count, and network egress affect stability.
1. First determine whether the node is slow or the usage environment is unstable
Many teams see latency values like 300ms or 500ms in the client and immediately assume the node is unusable. In reality, high latency may come from three types of causes: poor local network conditions, congested node routes, or abnormal team account environment. This is especially true when multiple people share the same subscription—frequent switching across regions, carriers, and devices can lead to unstable connections.
It is recommended to make a basic judgment first: test the same node on 2–3 devices. If everyone sees high latency, it is most likely a node or routing issue; if only one person has high latency, it is usually caused by the local network, DNS, client configuration, or system proxy conflicts.
2. Practical steps for teams to optimize node latency
- Prioritize nearby nodes: Users in mainland China should usually test regions such as Hong Kong, Japan, Singapore, and Taiwan first. Do not rely only on the node name—run actual speed and latency tests.
- Test repeatedly outside peak hours: Routes are more likely to be congested in the evening and during holidays. Teams should test at different times of day to avoid misjudgment.
- Use the client’s built-in latency test: Clients such as Clash, sing-box, and V2RayN usually support latency testing. After testing, sort by latency, then manually open webpages, videos, or work platforms to verify real performance.
- Do not put the whole team on a single fixed node: If many team members crowd onto the same node at the same time, the experience will likely degrade. Prepare 2–3 backup nodes and assign them by group.
- Update subscriptions and remove invalid nodes: If subscriptions are not updated for a long time, they may retain congested or unavailable nodes. It is recommended to update subscriptions regularly. This site also compiles free nodes suitable for testing, which can help with temporary troubleshooting.
3. How account environment stability relates to latency
When used by a team, the account environment is not just about “whether you can log in”—it also affects connection quality. Common issues include: too many devices using the same subscription at the same time, frequent cross-region logins, messy client rules, and multiple people modifying the same configuration file.
Too many devices make troubleshooting more complicated: some people use global proxy mode, some use rule-based proxy mode, and others enable browser proxy extensions, yet the final symptom is still “the node is slow.” It is recommended that the team standardize the client version and import method, and keep a record of each person’s network environment.
Frequent switching of egress regions can also affect how some platforms assess risk. For example, using a U.S. node in the morning, a Japan node in the afternoon, and then switching to a Europe node at night may trigger verification, rate limiting, or loading issues on the account. For work accounts, it is best to keep 1–2 commonly used regions fixed and avoid jumping around casually.
4. Recommended team troubleshooting checklist
- Have all members update to the same subscription first to avoid inconsistent node lists.
- Disable other proxy tools across the board, such as browser proxy extensions and older VPN clients.
- Test both “rule mode” and “global mode” separately to confirm whether split-routing rules are the cause.
- Change DNS, or enable remote DNS in the client, to reduce resolution issues.
- Record when high latency occurs, the node name, and the network carrier for easier comparison.
If troubleshooting shows that only one network environment has high latency, try switching between Wi-Fi and a mobile hotspot for comparison. If everyone is slow, the team should switch nodes or wait for the route to recover. The core of latency optimization is not blindly changing nodes, but standardizing team configuration, reducing fluctuations in the account environment, and keeping usable backup routes available.
