Major Internet and Cloud Outages
An archive of major internet and cloud outages since 2021, each told from the provider’s own incident report.
Every entry records what failed, when, for how long, which services went down, the root cause in plain English and what the provider said it would change. Times and durations are the provider’s own; where a report gives no clock times, the field is left empty rather than estimated. The archive covers AWS, Microsoft Azure, Google Cloud, Cloudflare, GitHub, OpenAI, CrowdStrike, Fastly, Meta and others, and new outages are added when the provider publishes its post-incident review.
Patterns repeat across the list: a configuration change that reached every region at once, a hidden dependency on one data center, a fix that needed the very system that was down. Our explainer on why one cloud outage can break unrelated apps walks through those dependencies.
