Article: When a Cloud Region Fails: Rethinking High Availability in a Geopolitically Unstable World

Rohan Vardhan — Wed, 22 Apr 2026 09:00:00 GMT

Sovereign fault domains are failure boundaries defined by legal, political, or physical jurisdiction rather than hardware topology. The article maps geopolitical events to known distributed-systems failure modes, argues multi-region should replace multi-AZ as the HA baseline for systems crossing jurisdictions, and outlines design patterns, chaos experiments, and an ALE model to justify the spend.
