Live status
This card reads OpenAI’s status page live when JavaScript is on. If nothing appears, open the page below.
What you notice says a lot about which side the problem is on. Kilobat checks both sides and says which.
An outage at OpenAI, or something on the path to it only: DNS, a VPN or proxy, a blocked host.
Why can’t it connect? checks every layer to Codex, then OpenAI’s status page. If the page reports an outage and nothing on your side failed, it says “Codex is down for everyone, not you”. Free
This network: an office, school, hotel or country rule, or its DNS.
Kilobat compares this network’s DNS with one encrypted lookup and tests the secure connection, then says “looks blocked on this network, not down”, with what it measured. Free
Your own line: Wi-Fi, the router, your provider or DNS. Not Codex.
Router and internet latency side by side show whether your own line is slow. Pro names the failing link, Wi-Fi, router, internet or DNS, with a fix. Free Pro
An outage at OpenAI, while your line is fine.
One notification per incident, such as “Claude Code: Anthropic reports an outage — not your connection”, and the MCP tool service_status for agents. Free
The path from your Mac to Codex: DNS, a VPN or proxy, IPv6, or the server’s answer.
“Codex’s status page reports no problems”, then the layer that broke and what to try next. Free
Codex loads only if every step works. A status page covers the last one; Kilobat checks the five before it too.
Why can’t it connect? Free
Name Codex and Kilobat checks your Wi-Fi, DNS, VPN and proxy, the connection and the server’s answer, then asks OpenAI’s status page. When the page reports an outage and nothing on your side failed, the verdict leads with it. When your Mac is the problem, it says so first.
# Is it them? OpenAI’s status page
$ kilobat down codexThe app’s proxy isn’t answering.
Why can’t it connect? Kilobat tests the request and path the app itself uses, its own proxy, IPv6 and tunnels included, and names the layer that broke.
What Kilobat watches
Kilobat matches apps and sites to the right status page by bundle ID and domain, so a failing Codex points at OpenAI’s status page, not a guess.
status.openai.com, run by OpenAI
The Codex app, by its bundle ID, and the codex process.
OpenAI’s page splits ChatGPT, Codex and the API into components. Kilobat counts only Codex’s: the web app, the CLI, the IDE extension and the API it uses.
The same status page also covers ChatGPT and OpenAI API.
If Codex won’t connect
From OpenAI’s own help pages, listed under Sources. Kilobat’s guides cover DNS, VPN and proxy trouble on a Mac.

The official answer is OpenAI’s status page, status.openai.com, which OpenAI’s team updates. The card at the top of this page reads it live in your browser and repeats only what it says.
When OpenAI’s status page reports no problems, the cause is usually on your side or on the way: your Wi-Fi or router, your provider, DNS, a VPN or proxy, or a network that blocks it. Try mobile data: if Codex works there, your network is the problem. Kilobat checks each of these and names the one that failed.
Connections from the Codex app, matched to OpenAI’s status page, counting only the components Codex Web, Codex API, CLI, VS Code extension and others. It checks your own line first, then asks the page.
Yes. When Codex keeps failing to connect while your own line is fine, and OpenAI’s status page reports trouble, you get one notification per incident. Turn it off in Settings.
OpenAI’s page splits ChatGPT, Codex and the API into components. Kilobat counts only Codex’s: the web app, the CLI, the IDE extension and the API it uses.
No. It sends a plain request to the status page, with no cookies and nothing about you, your network or your apps. Read the privacy notice.
Yes: the status checks, the notifications and Why can’t it connect? are free. Kilobat Pro, $29 once, adds findings with a fix for your own network, possible causes of call freezes and history.
