A major piece of the internet’s invisible plumbing faltered recently when Cloudflare (the infrastructure giant that protects and accelerates millions of sites) experienced a global outage that left users staring at error messages across the web. Platforms including X and OpenAI suffered elevated disruption, while some site owners couldn’t even access their dashboards.
Cloudflare eventually traced the root cause to a configuration file that ballooned beyond its expected size, crashing a key traffic-handling component. By mid-afternoon on the same day, the company announced a fix and apologised “to customers and the internet in general for letting you down today,” adding that it would learn from the incident.
To understand the wider implications, we asked two industry experts, Ross Moore, Information Security Researcher, and Ian Thornton-Trump, CISO at Inversion 6, for their take.
Here are their insights.
What Were the Most Critical Ripple Effects?
Moore says the first impact is psychological: a sudden erosion of trust in the services organizations heavily rely on. He notes the frustration of feeling locked in while knowing alternatives offer no guarantee.
“If one jumped ship to Provider B when Provider A went down, then not too long after, Provider B will go down; and if one moves to C, then the same thing is going to happen.”
He adds that business leaders feel exposed when their own promises of uptime depend on infrastructure they don’t control. Customers don’t see the dependency chain, only that “My promised service from ABC is down right at the instance I need it the most.”
Moore says the uncertainty is often worse than the outage itself: organizations can’t tell how long the issue will last, whether data is affected, or whether the failure is recoverable. That uncertainty forces teams to immediately push out holding statements and brace for support overload.
To him, the deeper issue is complacency: many businesses have become too comfortable assuming large providers are essentially invulnerable.
An Unavoidable Reality
Thornton-Trump frames the ripple effects through the lens of unavoidable reality: “Outages are going to be a part of life.”
He emphasizes that even the most robust cloud platforms are susceptible to mistakes and adversarial pressure. “We saw that with Microsoft Office 365 and DDoS attacks by Anonymous Sudan,” he notes, pointing out that the cloud’s overall resilience still stands, but not without risk.
For businesses running at high velocity, the ripple effects can be harsh: “If you’re doing transactions per second in the hundreds or thousands, an outage is really, really going to hurt the organization, right?”
He stresses that the business impact depends on volume, timing, and how well-architected the environment is for failover. For most consumer-facing services, temporary downtime is irritating but recoverable; for high-transaction platforms, the cost is immediate and material.
How can businesses strengthen their resilience and continuity plans to minimise disruption during major service outages like this?
Moore urges organizations to rebalance their security priorities. “When thinking of the famous CIA triad (Confidentiality, Integrity, Availability), the focus is often on Confidentiality and Integrity, such as encryption, proper access controls, environmental controls, and DLP.”
But he warns not to overlook availability, adding that availability should be placed on equal footing, especially given how frequent large-scale outages have been recently: CrowdStrike, AWS DNS, Azure, Cloudflare, “just to name a few.”
At this point, he says to perhaps even give equal weight to downtime risk as one gives to the other two aspects. “There will always be some dependency on a single point of failure, there will always be failures somewhere, and one never knows which will be the next failure.”
His message: “Expect at least one of your critical services to go down within the next few months.”
He notes that in on-prem environments, failures come in different forms (cut communication lines, power loss, cooling issues), but the effect is the same: downtime. His advice is to look hard at supply-chain dependencies and adopt the DAD triad (Disclosure, Alteration, Denial) as a complementary resilience lens.
“Don’t just plan for availability; plan for when availability fails.”
Mistakes Are Going to Happen
Thornton-Trump says resilience planning begins with accepting reality: “Mistakes are going to happen. Threat actors may try to find a chink in the armour.”
He places continuity planning squarely in the realm of business risk. For organizations running significant transaction volumes, the requirement is clear: “Go to your IT architects, go to your cloud architects and say, guys, we need to be multi-regional. We need to have resilience, and we need to be able to fail over.”
The “why” of an outage matters less than the ability to react: “It was really difficult to understand exactly why things were going sideways, but again, that doesn’t matter because all you needed to do was not use Cloudflare while they sorted their stuff out,” he adds.
Organizations must run their playbooks, have people who truly understand the infrastructure, and critically, implement their own monitoring: “It shouldn’t be a phone call when a person can’t reach the website. You should already know. There’s plenty of tooling, dashboards, reports, and monitoring services out there.”
He calls this a business-architecture conversation centred on tolerance, fault tolerance, and cost-aligned risk. Ultra-high availability is possible, but not free: “If you’re ready to pay for five nines or six nines of reliability, great. But again, that’s a big bill.”
And Thornton-Trump warns against resilience investments that defy economic reality: “There’s no point spending $2 million on protecting a service that brings in $250,000 a year in revenue.”
What broader lessons should organizations take away about dependency on single vendors and the future of internet infrastructure?
Moore argues that organizations should shift from reactiveness to readiness. Incident response must be real, rehearsed, and proactive: “Incident Response Plans should be ingrained enough to be a Response, not React, plan.”
He recommends developing templated comms and action frameworks around seven core categories:
- Availability and performance incidents
- Security and privacy incidents
- Data integrity and data-loss incidents
- Configuration and access issues
- Third-party and dependency failures
- Change and release incidents
- Planned maintenance and migrations
No organization can prepare for every failure, Moore says, but they can prepare for every type of failure.
Align Resilience to Business Reality
Thornton-Trump says the biggest lesson is aligning resilience to business reality, not fear or public pressure, and not technical perfectionism. Outages will continue to happen, but the key is proportionality.
From a consumer standpoint, he notes, downtime is rarely existential: “A system goes down or whatever. Yeah, okay, I’m going to come back a half hour later, an hour later, a couple hours later.”
But for platforms like Amazon or eBay, the stakes shift dramatically: “If you’re talking about hundreds of thousands of transactions going through your system and generating revenue, then you need to pull out all the stops.
“Outages are manageable. They have to be aligned to business risk.”
