Introduction
The first half of 2026 reinforced a key idea about Cloud and SaaS reliability - dependency risk. IncidentHub tracked 30,246 outages across 1,082 providers between January and June 2026. May was the busiest month, with 6,070 incidents. Cloud providers led in the total number of outages (4,723), followed closely by developer tools (4,589).
Besides volume, AI providers moved firmly into the production infrastructure layer with LLM outages resulting in disruption across EdTech, developer tooling, customer support, and communication tools. Automation created new failure modes of
its own: Google Cloud's May suspension of Railway's account resulted in almost all their workloads being unavailable. Edge and CDN incidents kept multiplying downstream, IAM remained a login bottleneck for entire product
stacks, and Canvas's May security incident took classrooms offline during exam season.
This report breaks down H1 2026 by layer - cloud, edge and DNS, IAM, developer tools, collaboration, AI, payments, observability, and EdTech - with the major incidents, category trends, and cascade patterns based on the data.
