GitHub's August 17 outage stretched to nearly eight hours partly because retries amplified the failure they were meant to survive. The fix has existed for a decade. Most client libraries still skip it.
Four AWS outages hit in eleven weeks in 2026: a data center overheating, a third-party network failure, a software limit, and a hardware routing fault. The standard fix, multi-region, would have caught exactly one.
A July 2 Railway outage report shows the real damage came after the fix: a containment decision that removed the last default route, and a well-known Linux default that turned a fallback path into a silent bottleneck.
A severed Zayo fibre route took down X, Zoom, Reddit, and Teams within minutes. Anycast and multi-region failover were never the layer protecting against this.
A single AWS zone failure turned into an 18-hour Coinbase outage. The postmortem reveals two specific ways 'multi-AZ' architecture quietly wasn't, and how to check your own systems for the same gap.
AI coding tools made adopting new technology feel fast. That's not the same as making it safe, and the distinction matters more now than it did before.
Most service timeouts are arbitrary numbers set once and never revisited. Here are the three failure modes that escape a misconfigured timeout — and how to calculate values that account for them.
AI coding tools are raising PR velocity across the industry. They are also raising incident rates by 243%. Here is what the data shows and how to read the tradeoff honestly.
At-least-once delivery is a guarantee, not a bug. Most webhook receivers in production are missing idempotency, dead-letter queues, or reconciliation. Here is the full checklist.
LLM features fail slowly, partially, and semantically — not with clean error codes. Designing for this requires different patterns from the distributed systems toolkit you already know.
