Cloudflare Outages in 2025: Key Findings
- Two Cloudflare outages within three weeks disrupted 20% of all websites, freezing ad delivery, breaking attribution, and stalling e-commerce checkouts.
- Tech leaders say marketers must now treat infrastructure redundancy as a strategic priority, not just an IT concern.
- The incidents highlight how centralized internet architecture creates single points of failure that can cost brands millions in lost revenue and eroded trust.
Update as of December 19, 2025: Cloudflare began scheduled maintenance at its MCI (Kansas City) datacenter between 10:00 and 22:00 UTC.Traffic might be re-routed from this location, potentially causing slight latency for end-users. PNI/CNI customers should expect network interfaces in this datacenter to temporarily fail over.
The internet recently had a reminder of its own fragility.
Cloudflare, the infrastructure provider sitting in front of roughly 20% of all websites, experienced two major outages within three weeks.
The November 18 incident lasted nearly six hours and disrupted major platforms, including ChatGPT, X, Spotify, and Shopify.
The 25-minute outage on December 5 also affected LinkedIn, Zoom, and countless other sites.

Neither incident was a cyberattack, and both were triggered by routine configuration changes that cascaded globally within seconds.
Some see these as isolated technical failures, while others view them as symptoms of dangerous centralization in internet infrastructure.
To understand what these outages mean for marketing operations, DesignRush spoke with ten tech leaders about infrastructure dependency and what agencies should do to prepare.
Why Centralized Infrastructure Creates Systemic Risk
The tech leaders we spoke with see these outages as symptoms of a deeper structural problem. David Barlev, CEO of Goji Labs, frames it bluntly.
"The Cloudflare outage was a stark reminder that even the biggest technical backbone is only as reliable as its weakest link," he said.
"When a single provider supports so much of the web, one error can ripple across the entire internet."
Goran Skorput, CTO of AI, Big Data, and Analytics at Kanda Software, says the fragility has been apparent to engineering teams for years.
"The modern internet is far more centralized, and therefore more fragile, than it appears," he noted.
"Although users interact with thousands of independent sites, a significant percentage rely on a handful of key infrastructure providers."
Over time, this drives demand for more resilient architectures such as multi-CDN strategies, decoupled marketing systems, and application designs that degrade gracefully when upstream dependencies fail."
Meanwhile, Yanosh Kunsh, CTO at eDesign Interactive, says the incident also exposed some "uncomfortable truths."
"The modern internet is far more centralized than most organizations admit," he explained.
"When a single point of failure sits underneath so many global platforms, the illusion of stability replaces the discipline of real contingency planning."
Cloudflare just suffered another major outage, taking down Fortnite, LinkedIn, Coinbase, and even Downdetector.

Andrea Okonkwo, head of brand and partnerships at Hugo, draws a comparison to the financial sector.
"It's quite reminiscent of the 'too-big-to-fail' scenario we saw with banks, but there's no FDIC for the internet," she highlighted.
"What's striking is that this wasn't an attack but routine configuration changes that cascaded globally within seconds, affecting a third of the world's most-visited websites."
Emerson Reyna, senior product owner at Designli, explains the deeper implications:
"The Cloudflare outage reveals a hard truth: the modern internet is powerful, but far more fragile than we like to believe," he added.
"Centralized infrastructure providers offer incredible speed, scale, and security but they also create massive single points of failure."
"We've become heavily dependent on a few cloud and infrastructure vendors, and when that provider goes down, the impact is immediate and widespread."
Chris Shyrock, director of support services at Atlantic.Net, underlines the hidden vulnerabilities the outages reveal.
"Even companies that don't buy Cloudflare directly can go dark because their SaaS tools, payment gateways, or analytics platforms do," he said.
"We've created a small number of choke points on the internet."
Shyrock further emphasizes that the marketing impact is immediate.
"If your site is unreachable, paid traffic still clicks on ads but lands on broken experiences. Tracking tags won't fire correctly, under-reporting conversions across platforms."
The Real Impact on Digital Marketing and eCommerce
When Cloudflare's network fails, digital marketing doesn't just pause. It breaks.
Ivan Dabic, CEO at BlueGrid.io, outlines the immediate consequences:
"Such outages instantly disrupt ad delivery, tracking, and online revenue.
They also push brands toward long-term resilience through diversification, server-side tracking, and multi-provider architectures."
Barlev emphasizes the trust erosion that follows:
"When foundational infrastructure goes down, ads stop running, purchases stall, and trust erodes in an instant.
Short-term, it's lost revenue, and long-term, it undermines confidence in digital commerce and delivery."
The timing of the November outage amplified its impact.
Occurring just days before Black Friday 2025, many retailers paused high-spending ad campaigns.
This disrupted revenue and also the algorithms that optimize ad delivery through the holiday period.
Industry estimates suggest the November outage cost eCommerce platforms between $180 million and $360 million in direct losses.
And some analyses even place Shopify's losses alone at over $4 million.
Why Users Don't Distinguish Between Brands and Providers
One of the most damaging aspects of infrastructure outages is how they affect brand perception.
"From a customer standpoint, users don't distinguish between 'your site is down' and 'Cloudflare is down.' They just know your brand failed them," Okonkwo pointed out.
"That's especially unforgiving during the holiday season, when intent is high, decision windows are tight, and tolerance for friction is effectively zero."
Alex Chaly, CTO at Shakuro, expands on how these disruptions affect user behavior beyond the immediate outage:
"When a provider like Cloudflare goes down, digital marketing and eCommerce don't just lose uptime. They lose continuity in user behavior.
We've observed this repeatedly across the products we maintain: attribution breaks, funnels stall, and real revenue is lost even after systems recover."
Kunsh, meanwhile, describes the broader economic freeze:
"An outage like this instantly freezes the digital economy. Ad delivery stalls, attribution breaks, campaigns lose momentum, and e-commerce conversion drops."
Building Resilience Into Digital Operations
The consensus among the experts we interviewed is that infrastructure dependency has become a real strategic marketing concern.
Josip Trbuščić, DevOps lead engineer at Infinum, recommends a proactive approach:
"Businesses should proactively identify critical dependencies and single points of failure within their systems."
Conduct risk assessment workshops to determine which services must remain functional during major outages. Engage with service providers to understand their redundancy strategies and contingency plans."
Chaly advocates for architectural changes.
"Long-term, this forces a deeper architectural shift toward multi-layer caching, provider redundancy, smarter routing, and edge strategies that prevent any single outage from stopping operations," he said.
Nazar Gulyk, founder at Empat, offers practical steps for marketing teams.
"Over time, outages like these push teams to build more redundancy into customer journeys — alternative landing pages, backup tracking paths, and clear customer-comms playbooks so you can react fast without losing trust."

I didn’t join @Cloudflare but here’s why the internet breaks every time Cloudflare goes down 👇
1. How Cloudflare Works (Super Simple)
Cloudflare isn’t just a CDN — it literally powers the internet.
CDN → Caches images, JS, CSS across 300+ edge servers
DNS →… https://t.co/mnHCAYCkF4pic.twitter.com/wWtl7VV565
Okonkwo predicts that resilience will become a competitive necessity.
"Built-in redundancy across hosting, CDNs, and payments will move from 'best practice' to competitive necessity," she explained.
"Brands will build around the assumption of periodic failure, engineering customer experiences that stay monetizable even when parts of the internet go dark."
Our Take: Is This the New Normal?
What strikes me most about these outages is that they happened twice in three weeks through nearly identical failure modes.
Cloudflare acknowledged in its December 5 post-mortem that the safeguards promised after November 18 were not yet in place.
For marketers, this is a signal that infrastructure reliability cannot be assumed, regardless of how established the provider might be.
Richard Ford, CTO at Integrity360, summarized the trend after the December outage.
"We are seeing the frequency increase as organizations put more eggs in fewer baskets, and as the complexity and the size and scale of operations like AWS, Google Cloud, Microsoft Azure, Cloudflare grow," he said.
The question for agencies and brands is no longer whether another major outage will occur.
It's whether your marketing infrastructure can survive when it does.
In other news, AWS experienced a similar outage in October, further highlighting the revenue loss brands face during widespread technical problems.
