Q4 2025 was a brutal quarter to be an enterprise IT leader. In October alone, AWS suffered a 15-hour DNS cascading failure that took down 141 services and impacted over 3,500 companies across 60 countries — Snapchat, Roblox, Fortnite, and airline reservation systems among them.
Azure followed days later with a networking configuration failure in its East US2 region that dragged on for nearly 50 hours. Cloudflare went down in November from a software defect triggered by a single database permissions change. Tens of thousands of SaaS outages occurred in 2025 alone.
