Mark Rafferty writes about the hidden weaknesses in the systems we rely on every day, especially in digital infrastructure and connectivity. His work examines how design choices, commercial pressures and technical dependencies can quietly introduce fragility into services assumed to be robust.

By exploring topics like shared infrastructure, network redundancy and the rising demands of AI workloads, Rafferty helps readers understand where resilience can fail in practice, and what questions to ask of the systems that underpin business, government and daily life. Reading these stories offers a grounded perspective on risk, reliability and the practical trade-offs involved in building truly resilient infrastructure.
