On November 28, the global financial system received a stark reminder of its profound dependence on physical infrastructure when a single data center failure brought one of the world's largest exchanges to a complete standstill. An outage at a CyrusOne facility in Aurora, Illinois, triggered a

Imagine a world where your internet connection never falters, no matter how many devices are online or how crowded your neighborhood gets with competing signals. That’s the promise on the horizon as Wi-Fi 8 and artificial intelligence (AI) gear up to transform the landscape of connectivity. Gone

Imagine a world where a single cyberattack on a power grid plunges an entire city into darkness, or a delayed emergency response due to network failure costs lives. This isn’t a dystopian fantasy—it’s a real and growing risk for critical infrastructure sectors like energy, public safety, and

Imagine a world where your network not only connects you to the internet but also predicts when a connection might falter, optimizes your data usage in real time, and tailors services to your exact needs before you even ask. This isn’t science fiction—it’s the potential future of

In an era where digital connectivity underpins nearly every aspect of business and daily life, network engineers grapple with challenges that grow more daunting by the day, driven by the relentless demands of cloud computing, artificial intelligence workloads, and edge technologies. Downtime isn’t

Imagine a world where the relentless hunger for digital innovation—fueled by artificial intelligence and cloud computing—pushes data centers to consume more energy than entire cities, yet the grid struggles to keep pace. This is the reality of today's tech landscape, where energy demands are

Imagine this: a quiet evening at home, streaming your favorite show, when suddenly a hacker slips into your WiFi network, silently siphoning off personal data or even manipulating your online activity. In today’s hyper-connected world, this isn’t a far-fetched plot from a thriller—it’s a very real

Imagine a world where farmers can predict crop failures before they happen, optimize every drop of water, and feed billions without harming the planet. This isn’t a distant dream but a reality unfolding right now in the digital agriculture sector. With the global population on track to reach 9.7

Procurement teams keep buying eye-popping accelerators and bigger nodes only to see throughput flatten, jobs stall on shuffles, and energy bills climb while GPUs sit idle because data movement and memory fit—not peak compute—call the shots. The paradox is familiar: systems look fast on paper yet

Rethinking what 5G is really for If 5G is not a single fast lane but three distinct performance profiles, which one matched the needs of a streaming platform, a robotic arm, or a citywide sensor grid—and what happened when the wrong lane was chosen? That question shifted the conversation from
