Weights & Biases Uptime History

Measured by PulsAPI's own checks, not reported by Weights & Biases. Every figure below is computed over the 90 days in the last 365 that PulsAPI actually observed, from 2026-05-30 to 2026-08-27. Days nobody watched are left out rather than counted as perfect.

Monthly Weights & Biases Uptime

Each month is the mean of its observed days. The strongest month was May 2026 at 100.00%, the weakest June 2026 at 85.84%. Months with few observed days are marked, because a short month is not evidence of a good one.

How This Weights & Biases Uptime Figure Is Measured

PulsAPI checks Weights & Biases every 60 seconds and records the result. A day's uptime is the share of that day's checks that came back fully operational, so a 20-minute outage shows up as a dip rather than being rounded away. The window figure is the mean of those daily values.

Two things this deliberately is not. It is not Weights & Biases's own published uptime, because vendors generally measure against their own SLA definitions, which usually exclude scheduled maintenance and often exclude partial degradation. And it is not a promise about the future: 90 days of history describes what happened, and the useful way to read it is alongside the incidents behind the dips.

Uptime measured this way is a mean of component uptimes where a vendor publishes components, so coverage matters as much as the percentage. That is why the observed-day count sits beside every figure on this page rather than in a footnote.
