Cerebrasdown detector & server status
Is Cerebras down or not working right now? This live Cerebras down detector combines Cerebras's official status feed, our own independent checks, and first-party user reports — and shows whether it's the CerebrasAPI, the app, or a specific capability that's affected, plus the upstream AI provider it depends on. Use it to tell whether Cerebrasis having an outage today, and whether it's down for everyone or just you.
Crowd signal — your reports, not our automated checks.

13,077reachable checks. The line plots the median of each interval, so one timeout can't spike it, and we lead with the median rather than an average, which a single slow response would skew. Failed checks are excluded: a timeout is not a response time.
Responding normally (~152 ms typical).
Uptime & history
Tracking since Jun 22, 2026% of our checks that found Cerebras fully operational — a degraded check counts against it, because a slow or partly-broken service is not a working one. Down and degraded time are counted at our 5-minute check resolution, so both are approximate. Longer windows fill in as data accrues — we never show uptime we haven't measured.

What this page can and can't tell you
- How we decide. We combine Cerebras's official status feed, our own independent check from US East (Virginia), and first-party reports from readers. The confidence badge shows how many of those signals agree.
- On root cause. We have no visibility inside Cerebras's systems. We report what the signals show rather than guessing at an internal cause.
- Outages are rarely all-or-nothing. Some are regional. Some hit one surface while the rest works, so the Cerebras API can fail while the app is fine. The capability panel breaks it down.
- Green doesn't mean everyone. If our check reaches Cerebrasbut you can't, the problem is more likely local: your network, a VPN, browser extensions, or cache.
Frequently asked
Is Cerebras down right now?+
Right now, Cerebras appears to be operational. Cerebras looks healthy. The official status page reports all systems operational and our independent checks are passing.
Is there a Cerebras down detector?+
Yes — this page is a live Cerebras down detector. It combines Cerebras's official status feed, our own independent reachability check, first-party user reports, and the AI dependency graph, then shows a confidence level so you can tell a real outage from a local glitch. Cerebras is currently operational. We only show signals we can actually verify — never invented report totals.
Is there a Cerebras outage today?+
No active Cerebras outage is detected right now — it appears operational. For past incidents and dated outage recaps, see Cerebras's status history below.
What is Cerebras's server status and API status right now?+
Cerebras is currently operational. Server status and API status aren't always the same — the Cerebras API can fail while the web app works, or vice-versa. The capability panel on this page breaks status down by surface (API, app, and any image/voice features) so you can see exactly which part is affected.
Is the Cerebras API down? (Cerebras API status)+
Check the API row in the capability panel above — Cerebras is currently operational overall, but the API can carry its own status. For developers, "Cerebras API status" problems usually surface here first, because we read Cerebras's own status feed and watch the API surface directly.
Why is Cerebras slow or not working?+
Common causes are an upstream provider incident, API rate limits during peak demand, a regional CDN issue, or maintenance. Cerebras is currently operational. We show the official status, our independent check, and a confidence level so you can see which signals point to a real problem.
Is Cerebras down for everyone or just me?+
We check Cerebras from our own servers, independent of your device or network, and combine that with Cerebras's official feed and user reports. If our independent check reaches Cerebras but you can't, the problem is most likely local — try a different network, disable a VPN/extensions, or clear your cache. If our check and the official status both show problems, Cerebras is down for everyone.
How can I tell if it's Cerebras or my own connection?+
AIDownCheck runs an independent reachability check from our own servers, separate from Cerebras's official status page. If our check passes but you still can't connect, the problem is more likely local — try a different network, clear your cookies, disable VPN/extensions, or use a different browser. If our check is failing too, it's more likely Cerebras's side.
What can I use while Cerebras is down?+
Good alternatives include Groq, SambaNova. We track their live status too, so you can switch to one that's currently operational.
Where is Cerebras's official status page?+
Cerebras's official status page is at https://status.cerebras.ai. AIDownCheck reads it automatically and combines it with our own checks — so you get the answer without juggling tabs.
