For a moment on Tuesday night, travellers at Perth Airport found themselves staring at blank screens, looping error pages and glitching flight updates. The cause wasn’t a hacker, a cyber-attack or a national emergency. It was a glitch in a company headquartered 15,000 kilometers away — Cloudflare, an infrastructure giant many passengers had never heard of until it broke. Nothing crashed. No flights were grounded. But for cybersecurity researchers, aviation analysts and digital infrastructure experts, this was a warning event — and a serious one. Because what went down wasn’t the airport. It was the illusion that everything was secure. (Cloudflare Outage Perth)
How a single Cloudflare failure reached Perth’s runway screens – Cloudflare Outage Perth
Cloudflare distributes traffic and provides security layers for millions of websites and platforms — including airport service providers, airline portals and flight information systems. So when a configuration file inside its network spiraled out of control, it didn’t just break gaming websites and social platforms. It broke parts of critical transport infrastructure.
A senior Perth Airport contractor (name withheld due to contractual restrictions) described it bluntly:
“It wasn’t dangerous this time. But swap ‘internal error’ with ‘malware’ or ‘targeted disruption,’ and we’re talking about a national incident.”
That’s the fear: the outage wasn’t bad enough to trigger real-world chaos — but it was close enough to show how easily it could (NewsonAu).
What happened — Cloudflare Outage Perth
When Cloudflare went down, most services in major cities had alternate paths or redundant infrastructure. But Perth? Perth relies heavily on long-distance routing and cloud-based systems. When upstream infrastructure breaks, Perth isn’t slowed down — Perth is isolated.

“This is what a dry run looks like” – Cloudflare Outage Perth
Cybersecurity analyst Dr. Aileen Morgan from UNSW calls this a “dress rehearsal for a real cyber crisis.”
“The outage showed every point of dependency. If the same disruption had been caused intentionally or lasted longer, aviation operations and emergency logistics could absolutely be compromised.”
Her biggest concern is not the outage itself — but the lack of public infrastructure transparency. Australians simply do not know how many public services depend on foreign routing companies.
A transport system designed for convenience (Cloudflare Outage Perth)
Modern airports were built for efficiency: cloud check-in, online manifests, connected logistics.
The Cloudflare outage proved that we inverted a basic principle:
✘ Instead of the internet existing to support airports,
✔ Airports now exist in reliance on the internet.
This has huge implications for:
- Cybersecurity
- Emergency response
- National mobility
- Border security
- Supply chains
And nowhere is this more visible than in Perth — the most digitally isolated major metro in the country.
If this had lasted six hours instead of two… : Cloudflare Outage Perth
This is where the nightmare scenarios begin.
Experts warn that if the same outage had lasted just a little longer, the cascading failures could have been catastrophic. We’re talking about frozen airline check-in systems, delayed cargo and critical medical transport, broken flight-scheduling platforms, confused emergency rerouting, compromised aviation data reporting, and even airport staff being forced to switch to manual processing at scale.
At that point, it’s no longer a minor inconvenience — it becomes a full-blown systemic disruption with real safety and economic consequences.
WA’s geography makes the risk worse
Perth has:
- Fewer data centres
- Longer routes to east-coast infrastructure
- Limited sovereign cloud options
- Higher latency dependency
- Fewer redundant networking paths
When a global edge provider goes down, Perth takes the first punch, hardest.
As one industry veteran put it:
“Sydney goes slow. Perth goes dark.”
This outage wasn’t malicious — which is exactly why it’s frightening
No hostile state, no ransomware and no actor exploiting a zero-day.
Just misconfiguration.
If that can break aviation systems, imagine what a deliberate attack could do.
The Cloudflare outage was not a catastrophe.
Flights continued to land safely, airport screens eventually rebooted, and most websites came back online without lasting damage.
However, the incident exposed an uncomfortable truth: if this outage were a real stress test — even unintentionally — Australia would not have passed.
Perth Airport itself did not fail.
But the systems surrounding it showed enough cracks to highlight how vulnerable the broader infrastructure actually is. The reliance on external cloud services, the lack of local redundancy, and the slow recovery time all demonstrated how easily essential operations could be disrupted.
In other words, nothing major went wrong this time — but we were given a clear preview of what could go wrong in a longer or more severe outage.
That’s the part we can’t afford to ignore.
