Three things AI tools need from a route
The same route that loads web pages smoothly can stall on an AI tool's sign-in screen or halfway through an answer. The reason: AI tools put three demands on the connection at once — region checks, IP risk scoring and long-lived connections.
First, region checks. Most AI tools use the location tied to your exit IP to decide whether you can use the service and which features you get. The exit country also shapes the interface language, the models on offer and some feature entry points. If your route exits in a country outside the supported list, the page will simply say the region isn't available — switch to a route that exits in a supported country. Bandwidth has nothing to do with it.
Second, IP risk scoring. Risk systems look beyond location: how many people have used that IP, and whether there have been unusual sign-ins lately. Heavily shared data-centre IP ranges tend to trigger extra verification, and signing in to the same account from several countries in a short window will do the same. Pick one route and stay on it for a while instead of switching regions on every connection.
Third, long-lived connections and streaming output. AI replies arrive token by token, so a single hiccup shows up as an answer that stops mid-sentence, hangs on "Generating…" or has to be regenerated. Bandwidth is rarely the issue here — link stability is. Fewer cross-border hops and better-controlled relay nodes mean less packet loss and jitter. It shows most at peak hours, which is exactly why dedicated and relay routes exist.
One more point that's easy to miss: uploading images, documents and voice notes uses upstream bandwidth. On the same plan, dedicated routes usually offer more upstream headroom than standard relays, and the difference is obvious with large files.
Tool by tool: where each one gets stuck
The six tools care about different things. Below, each is covered in terms of what it's sensitive to and how to configure for it — no account-level tactics involved.
Sign-up and sign-in are where region checks bite hardest; during use, the main risk is a dropped long connection. Chat, file uploads and voice all run over the same session, so one hiccup on the route cuts the whole answer.
- Region: exit in a supported country, and keep sign-up, sign-in and daily use in the same one
- Route: prefer an IEPL dedicated line or a native-IP direct route to cut cross-border hops
- Watch out: signing in from a different country each time tends to trigger extra verification
Region checks are just as strict, and long-document work stretches a single session out — one analysis can run for several minutes, so link stability matters more than peak speed.
- Region: same as ChatGPT — the exit country has to be on the supported list
- Route: dedicated first; a drop mid-session wastes the whole analysis
- Watch out: large uploads depend on upstream bandwidth, so pick a route with headroom
It's tightly bound to an account system, so staying signed in depends on the whole chain of related services being reachable. A common pattern: the page loads but the sign-in step spins forever — usually one leg of the path is blocked rather than the region being rejected.
- Region: sign in and use it from the same region so the session doesn't drop
- Route: relay or dedicated both work; what matters is a complete, stable path
- Watch out: browsers cache region data — after switching routes, clear the site's data and try again
It works inside the editor in a way where nearly every keystroke can fire a request, making it far more latency-sensitive than chat tools. Every extra millisecond of routing shows up as time spent waiting for a suggestion.
- Region: pick an exit country that the plugin and your account actually support
- Route: prefer nearby regions (Japan, Singapore, Hong Kong) to cut round-trip latency
- Watch out: plugins usually ignore the system proxy and need their own setting in the editor
Once a job is submitted there's a waiting period; dropping the connection won't cancel the job, but downloading the finished images will fail. Image files are large, so data use runs an order of magnitude above plain text chat.
- Region: stay within the supported list, and use the same route for submitting and downloading
- Route: bandwidth first — most noticeable when downloading results
- Watch out: heavy image generation eats plan data; if you run out, you can top up with a data pack
One tool carries three kinds of traffic: in-editor completions, sidebar chat and commands run in the terminal. They may not share an exit — completions follow the plugin's own settings, while terminal commands follow environment variables.
- Region: stick to one route so completions and chat don't exit from different places
- Route: low latency first, long-connection stability second
- Watch out: plugin and terminal proxies are configured separately — see the developer section below
Things to watch during sign-up and sign-in
The place AI tools break most often isn't during use — it's sign-up and sign-in. That's when risk systems look closest: IP location, IP history and how the account maps to that IP all feed the decision.
One route from start to finish. Sign-up, the first verification email and the first sign-in should all happen in the same region on the same route. Switching countries midway tells the risk system the account is active in two places at once, and a string of verification prompts usually follows.
Don't switch routes mid-verification. If a tool asks for an extra check, complete it on the route you're already on. Don't hop to another country to look "cleaner" — the hop itself is the anomaly.
Signing up for this service is simple: no email address required — just a username and password. One less email step, and one less flow that can stall when a message never arrives. Once you're set up, your subscription syncs in the client, so there are no nodes to paste by hand.
Browsers cache region-related site data. If a page still says your region is unavailable after you switch routes, clear that site's cookies and site data, then reload.
Web app vs API: different requirements
For the same tool, the web app and the API are two entirely different paths, and the problems they hit barely overlap.
The web app runs in a browser: a full TLS session, long-lived connections, streaming rendering and a browser fingerprint on top. Region checks go by exit IP, while risk scoring also reads the browser environment. Web app problems usually look like "the page loads but the feature doesn't work" or "the answer stops mid-sentence".
API calls come from a program: auth details in the request headers, each call a separate short request, with timeouts controlled by the client. APIs suffer more from timeouts and failed TLS handshakes — many SDKs default to a timeout of just tens of seconds, so one jittery moment throws an error, and retries stack up more waiting. Note too that the exit IP of the machine running the code is what counts: something that works from a local dev machine may fail once it moves to a server in a data centre.
What matters for the web app
Exit IP location, browser cache, long-connection stability and upstream bandwidth when uploading files. Pick one route with the right region and stay on it, and clear site data after any switch.
What matters for the API
Whether the exit IP is fixed, how smoothly TLS handshakes complete, client timeout settings and retry policy. Give any machine that calls AI services one fixed route rather than switching exits often.
If you need both, the easiest setup is two routes in the same region: a dedicated line for the web app to keep long sessions alive, and a stable relay for the program so its exit stays fixed.
Developer setups: command line / IDE plugins / CI
Traffic exits are messier in a dev environment than in a browser, because every tool reads proxy settings differently.
Command line. Most CLI tools ignore the system proxy and only read environment variables. Set HTTPS_PROXY and HTTP_PROXY explicitly in your terminal, and add ALL_PROXY if you need to cover every protocol. Before running the real task, check the exit with curl -I against a known address — it saves a round of troubleshooting.
IDE plugins. Editor plugins usually have their own proxy settings that ignore the system proxy. In VS Code and its forks, search for proxy in settings and enter the same address you use in the terminal. JetBrains IDEs have a separate setting under Appearance & Behavior → System Settings → HTTP Proxy. Completions use the plugin's own connection, so if chat works but completions don't, check here first.
CI and automation. Continuous integration usually runs in a data centre, where IP ranges are shared by many users and risk systems take notice. Workable options: run AI-dependent jobs on a self-hosted runner, or set the exit explicitly in the pipeline. One more reminder: never put your subscription URL in any file in the repo — use a placeholder in examples, such as https://example.com/sub?token=YOUR_TOKEN.
A subscription link is as good as account credentials. Put it in a public repo, a screenshot or a ticket and you're handing your routes to someone else. If a colleague needs access, have them get their own subscription from their own account.
Tools × routes comparison table
The table below suggests a direction for each way of working. You can switch freely between these routes on one subscription — no separate purchase per tool.
| Tool | Usage pattern | Suggested route type | Region | Main focus |
|---|---|---|---|---|
| ChatGPT | Chat · web / mobile | IEPL dedicated | Japan / Singapore / United States | Region checks + stable long connections |
| Claude | Chat · long documents | IEPL dedicated | Japan / United States | Uninterrupted long sessions, upstream bandwidth |
| Gemini | Chat · tied to an account system | Relay | Singapore / United States | Complete sign-in path, session persistence |
| Copilot | IDE completions | Relay / direct | Japan / Hong Kong / Singapore | Low latency, plugin-specific proxy |
| Midjourney | Image generation · result downloads | Direct / dedicated | United States / Japan | Bandwidth and data use |
| Cursor | Completions + chat + terminal | IEPL dedicated | Japan / Singapore | Consistent exits, terminal proxy setup |
Route types: an IEPL dedicated line runs on its own channel and is the most stable; a relay forwards through an intermediate node, balancing cost and stability; a direct route lands straight away with low latency but is more exposed to cross-border fluctuations. See the routes page for the full list.
Common failures and what causes them
Match the symptom to the stage first; in most cases switching routes or changing one setting fixes it.
| Symptom | Likely cause | What to try |
|---|---|---|
| Page says your region isn't available | Exit IP is outside the supported area, or the browser cached an older region | Switch to a route that exits in a supported country, clear the site's data and retry |
| Repeated verification prompts after sign-in | Exit IP changes often, or that IP has been heavily used lately | Stay on one route for a while and avoid country-hopping in a short window |
| Answers stop mid-sentence or hang on generating | Jitter breaks the long connection, worst at peak hours | Move to an IEPL dedicated or relay route and avoid congested hours |
| File or image uploads stall | Not enough upstream bandwidth | Switch to a dedicated route with more upstream headroom, or upload smaller files |
| Command-line tools ignore the proxy | CLIs don't read the system proxy, only environment variables | Set HTTPS_PROXY / HTTP_PROXY explicitly, then verify the exit with curl |
| IDE completions are slow while chat works | The plugin uses its own proxy settings and doesn't follow the system | Enter the proxy address separately in the editor's settings |
| API requests time out | Jitter on the link plus a short client timeout | Fix the exit route, raise the timeout a little and set a limited number of retries |
How to choose: advice by use case
You don't need a separate route per tool. Four use-case groups cover everything on one subscription.
Chat-first
ChatGPT, Claude, Gemini. Choose an IEPL dedicated line that exits in a supported country and holds long connections, and stay in one region from sign-up through daily use. This group doesn't care about peak speed — it cares about not being interrupted.
Coding-first
Copilot, Cursor and command-line tools. Prioritise low-latency routes in nearby regions — Japan, Hong Kong and Singapore work best — and set the terminal and plugin proxies separately.
Image generation and media
Tools like Midjourney where images are the main output. Bandwidth and data come first, and the difference shows when downloading results. If data runs low, top up with a data pack — use it at your own pace, it never expires.
Development and automation are a category of their own: a fixed exit and a stable link matter most, speed comes third. Giving task-running machines their own route is easier than sharing one with a browser.
Exit cities and route types are listed one by one on the routes page; plan prices and data tiers are on the plans page — from ¥9.9/month with 60GB included, plus 300GB / 1000GB / 3000GB data packs. Every plan comes with a 7-day refund, no questions asked, and sign-up needs no email address.
FAQ
The five questions we hear most about pairing AI tools with a route.
Can I run ChatGPT and Cursor at the same time on one subscription?
Yes. This service has no device limit, so every device on the same subscription can connect on its own, and different devices can use routes in different regions. One caveat: keep the same account in one region on the AI tool's side to avoid extra verification.
Do I need to buy a separate route for each AI tool?
No. You can switch routes freely in the client, across 110+ countries and 150+ routes, at no extra cost. What you actually use up is data, which resets monthly on your activation date.
The web app works but API calls always time out — how do I troubleshoot?
First check whether the machine making the requests exits from the same IP as your browser — often the code runs on another machine or in a data centre. Next, look at the client timeout: when the link jitters, a short timeout throws an error straight away. Finally, check that TLS handshakes complete smoothly, and switch to a route with a fixed exit if needed.
How is data counted, and what happens if I run out?
Monthly plan data resets each month on your activation date and doesn't roll over. Image generation and large uploads use far more than plain text chat; if you're running low, top up with a data pack: ¥158/300GB, ¥358/1000GB, ¥658/3000GB — use it at your own pace, it never expires.
Will switching routes mid-session sign me out of an AI tool?
The occasional switch is usually fine, but hopping across several countries in a short time tends to trigger re-verification on the tool's side. For everyday use, stay on one route and save switching for when you genuinely need a different region. If you're already seeing repeated prompts, staying on one route for a while settles things down.
