The AWS Outage That Broke the Rules of Multi-AZ [MUzGNMymYwM]
Coinbase had Multi-AZ enabled on AWS. Their trading engine still went dark for 7 hours. When a North Virginia data center overheated and multiple availability zones in US-EAST-1 crashed simultaneously, the failover paths engineers expected simply didn't exist. The hard truth? Multi-AZ protects you from one zone failing. It doesn't save you when multiple zones go down, especially if critical services (like your RDS primary or fixed ECS tasks) are single-zone by design. Resilience isn't something AWS gives you—it's something you build. Multi-AZ is just the floor. Let me know in the comments: What’s the longest outage your team has ever had to recover from?
