The internet experienced a worldwide flare-up this month when Cloudflare, "the immune system for the internet" experienced a global outage that rendered websites and services such as X (formerly Twitter), ChatGPT, Bet365, Sage and Spotify unreachable. You know things are bad when Downdetector, the website dedicated to monitoring and reporting outages, is itself down because of one. And while the cause was found to be an internal configuration file issue rather than the result of a cyber attack or bad actors, it has again raised concerns about the worldwide reliance on and resilience of such services - especially in the wake of the AWS outage just last month.

"The Cloudflare outage is another stark reminder of how dependent global systems have become on a small number of critical internet infrastructure providers," commented Douglas Wadkins, CTO, Opengear. "These providers power essential background services for many websites, so any disruption causes these sites to stop working immediately." He adds that "The ability to access systems remotely, isolate the cause and remediate quickly is what stops a single point of failure from spiralling into a widespread outage. In our hyper-connected world, where global supply chains and digital networks are deeply intertwined, even brief disruptions can have far-reaching economic, operational, and geopolitical consequences in an already fragile climate."

For Stewart Laing, CEO at Asanti Data Centres, the outage underlines how the UK's digital infrastructure is reliant on a handful of global platforms: "When a single provider falters, the consequences reverberate far beyond websites loading slowly - payment platforms stall, logistics systems pause, customer services disappear and entire digital journeys simply stop. Cloudflare isn’t the only provider facing these pressures. The sheer scale and concentration of traffic running through a small number of cloud and network giants means any disruption will always ripple outward. What we’ve seen again is that resilience is fundamentally about whether organisations have built real architectural diversity into their IT estates."

This is echoed by Rob Demain, CEO at e2e-assure, who observes that "Cloudflare is a large, U.S. company and when issues like this occur it highlights how dependant the U.K. is on U.S cloud providers, who offer services for economic prosperity and cyber security. This is a reminder of how fragile our digital systems can be and how much we rely on just a few key players to keep the internet running smoothly." Perhaps the internet's 'immune system' needs a booster before the next major outage catches us all cold.
