In nine days, two of the world's three largest cloud providers suffered major outages. Meanwhile, ransomware hit its highest monthly count: 86 publicly disclosed incidents, 623 total attacks. Your infrastructure was vulnerable everywhere.

AWS — 20 October

15-hour outage. US-EAST-1. 1,000+ companies disrupted, 17 million user reports. Root cause: an empty DNS record.

Azure — 29 October

Nine days later: Azure Front Door configuration change cascaded globally. Microsoft 365, Teams, Xbox Live offline — on earnings day.

What to build

  1. True multi-cloud isolation. Not multi-region within one provider.
  2. Assume your cloud will go down. 24-hour graceful degradation.
  3. Offline backups, tested monthly. Air-gapped.
  4. Run chaos engineering. Simulate cloud going dark.
