Separate the IP, the account, and the incident
| What it looks like | What it resembles | Do this first |
|---|---|---|
| Entry returns 403 or fails to open at all; another network restores it instantly | A restricted exit | Single-variable network switch; record both exits |
| A ban or violation notice after sign-in; other accounts on the same network work | An account-level restriction | Follow the notice and official channels; network checks cannot substitute |
| Everyone fails at once and the status page shows an incident | A service-side outage | Wait for recovery; incidents cause the most false ban reports |
| Usable but repeated verification challenges | Risk-control friction, not a ban | See the verification-loop guide; do not rotate exits |
| Only one feature fails, such as uploads | A feature-path problem | Unrelated to the exit; do not change networks over it |
Does ChatGPT restrict IPs: what can and cannot be confirmed
OpenAI does not publish IP-level rules and will not confirm whether a specific exit is restricted. The official forums have long carried my-IP-got-blacklisted reports, mostly on shared exits: data-center ranges and VPN pools get blacklisted in bulk after abuse, catching every user who happens to sit on the same exit.
The official network-recommendations page treats connection errors as a connection-layer problem: rule out the browser and the local network first, then follow the error message. A failure to connect is therefore not automatically an account-level ban, and the two have entirely different paths.
Risk signals are not a ban: how this relates to IP-risk results
The data-center, proxy/VPN, and risk-source labels on the ChatGPT IP check are network signals: they explain why an exit attracts more friction, but they do not prove a ban. A clean residential exit can be restricted after bulk abuse, while a proxy-labeled exit may keep working.
The order of judgment therefore is: use the comparisons in this guide to place the failure in a layer first, then use the risk signals to explain why this exit. Treating a signal as the verdict produces the wrong chain: I am on a data-center IP, therefore I am banned.
How to check whether your current exit is the problem
Reproduce in a clean browser
A private window or an extension-free browser rules out cookies, scripts, and extensions. If the clean environment works, the problem is local, not the exit.
Change only the network
Switch to a phone hotspot and nothing else. Results changing with the network is the precondition for suspecting the exit; if nothing changes, stop working on the IP.
Record both exits
Run the ChatGPT IP check on both networks: IPv4/IPv6, ASN, data-center or residential attributes, and proxy signals. Evidence must come in pairs to compare.
Rule out incidents first
During weeks when ChatGPT-down searches spike, many ban reports are outages. An all-clear status page does not exclude local failures, but it keeps a known incident from being read as a ban.
What to do after a restriction, and what not to do
- Keep evidence: the error page, the timestamp, and the paired results from both networks.
- After switching exits, observe for 24-48 hours; many restrictions are temporary, so do not conclude on day one.
- If one exit stays broken, report it to official support with evidence (error text, time, exit ASN) rather than saying the IP is dirty.
- Do not cycle through nodes; it hides the problem and can land you on a worse shared exit.
- Do not buy clean-IP guarantees; network attributes are measurable, but nobody can guarantee an account outcome.
- Go through the official appeal channel only when the notice itself points to the account.
