Methodology
- Probe
- We send a GET request to the target URL with each probe method and time the full response.
- Counts as DOWN
- Every probe method fails the request (connect refused, DNS error, timeout, or HTTP 5xx).
- Counts as DEGRADED
- At least one probe method succeeds but at least one fails, the site is up but blocking or mishandling a specific request type.
- Detail
- Per-method results include HTTP status code, response time, and best-effort DNS / connect / TLS / first-byte phase timings when the Node HTTP client exposes them.
- Cadence
- Every 5 minutes, in parallel across 4 independent probe methods (HTTP/1.1 with strict TLS, HTTP/2, a browser User-Agent GET, and a curl-style HEAD) from our edge network. We check probe diversity, not geography — if a site blocks a non-browser User-Agent or only speaks HTTP/1.1, the four cards show it.
- Rate-limited targets
- If a host returns 429 or consistently drops connections from our IPs, we cap retries at 3 and report the last observed status, we do not flood the target to confirm the outage.
- Data source
- Our verdict is based on direct multi-method probes, every result above is a live network request, never a Twitter mention or DownDetector aggregate. User reports, when shown, appear separately below as a supplementary signal and are never used to determine the up/down verdict.

Common questions
Is OpenAI API down right now?
We have not completed a probe of openai yet. We have not built up enough probe history for openai yet to quote an uptime figure — the numbers above are from the most recent check only. Every figure on this page comes from our own HTTP requests to openai — four independent probe methods (HTTP/1.1, HTTP/2, a browser User-Agent GET and a curl-style HEAD) — not from user reports or a third-party feed.
Is OpenAI API down for everyone or just me?
If all four probe methods above show a response, OpenAI API is reachable from our network and the problem is local to you: flush your DNS cache, switch networks, disable a VPN, or try another browser. If two or more methods failed, the problem is on OpenAI API's side. When every method fails at the connection level we say "unreachable" rather than "down for everyone" — some large sites block monitoring networks at the edge while serving browsers normally, and we would rather be precise than dramatic.
How reliable has OpenAI API been recently?
We do not have enough history for openai to answer that honestly yet. This page fills in as our monitoring accumulates checks; the 30-day strip above shows exactly which days we have data for.
