Is Weights & Biases down?

Right now, Weights & Biases appears to be degraded — some users may see errors or slowness. Weights & Biases's official status page is reporting degraded performance ("Partially Degraded Service"). Our independent checks can still reach Weights & Biases, so some surfaces may still work.

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.

Common causes are an upstream provider incident, API rate limits during peak demand, a regional CDN issue, or maintenance. Weights & Biases is currently degraded. We show the official status, our independent check, and a confidence level so you can see which signals point to a real problem.

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.
