Retrospective edition: 2026-01-05. Source published: 2026-01-05. Added to this archive: 2026-11-03. This briefing was prepared later from the linked announcement; it was not published on this website on the historical edition date.

The update introduces three metrics—Spot Total Count, Spot Total Interruptions, and Spot Interruption Rate—enabling comprehensive tracking of Spot instances running within selected time frames and interruption patterns across availability zones and accounts. This data assists organizations in identifying capacity availability and managing disruption risk.

With these metrics, customers can refine Spot instance strategies by diversifying instance types, spreading workloads geographically, or using Spot placement scores to access higher availability capacity pools. The feature is enabled by default at no added cost in all AWS commercial regions, integrated within existing EC2 Capacity Manager tools.
