Is Weights & Biases down?

Right now, Weights & Biases appears to be operational. Weights & Biases looks healthy. The official status page reports all systems operational and our independent checks are passing.

Yes — this page is a live Weights & Biases down detector. It combines Weights & Biases'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. Weights & Biases is currently operational. We only show signals we can actually verify — never invented report totals.

No active Weights & Biases outage is detected right now — it appears operational. For past incidents and dated outage recaps, see Weights & Biases's status history below.

Weights & Biases is currently operational. Server status and API status aren't always the same — the Weights & Biases 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.

Check the API row in the capability panel above — Weights & Biases is currently operational overall, but the API can carry its own status. For developers, "Weights & Biases API status" problems usually surface here first, because we read Weights & Biases's own status feed and watch the API surface directly.

Common causes are an upstream provider incident, API rate limits during peak demand, a regional CDN issue, or maintenance. Weights & Biases 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.

We check Weights & Biases from our own servers, independent of your device or network, and combine that with Weights & Biases's official feed and user reports. If our independent check reaches Weights & Biases 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, Weights & Biases is down for everyone.

AIDownCheck runs an independent reachability check from our own servers, separate from Weights & Biases'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 Weights & Biases's side.

Good alternatives include DataRobot, Langfuse. We track their live status too, so you can switch to one that's currently operational.

Weights & Biases's official status page is at https://status.wandb.com. AIDownCheck reads it automatically and combines it with our own checks — so you get the answer without juggling tabs.
