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

Uptime & history
Tracking since Jun 22, 2026% of our checks that found Weights & Biases 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 Weights & Biases'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 Weights & Biases'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 Weights & Biases API can fail while the app is fine. The capability panel breaks it down.
- Green doesn't mean everyone. If our check reaches Weights & Biasesbut you can't, the problem is more likely local: your network, a VPN, browser extensions, or cache.

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.
What is Weights & Biases's server status and API status right now?+
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.
Is the Weights & Biases API down? (Weights & Biases API status)+
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.
Why is Weights & Biases slow or not working?+
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.
Is Weights & Biases down for everyone or just me?+
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.
How can I tell if it's Weights & Biases or my own connection?+
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.
What can I use while Weights & Biases is down?+
Good alternatives include DataRobot, Langfuse. We track their live status too, so you can switch to one that's currently operational.
Where is Weights & Biases's official status page?+
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.
