ProbegradeThe Probegrade Report
A monthly, dated reliability edition.
At the end of each month we freeze scores from that month's archived probes into a citable edition. Providers can embed a dated badge, so a score is always tied to when it was measured.
Dated
Each edition is labeled by month. A badge from October says October, so stale claims can't masquerade as current.
Auditable
Each edition lists the hash of the probe archive it was built from.
Citable
Every edition has a stable URL and a suggested citation for writers, analysts and agents.
Dated badges
Example only. Badges show the score frozen in that month's edition.October 2026 · sample
