On Tuesday afternoon, the Internet was brought to its knees. Cloudflare, a company that secures approximately 20% of all websites in the world, experienced a spectacular failure. Effect? ChatGPT, Portal X, Zoom, Canva and even Downdetector (the irony of fate!) have given up on thousands of users. A deliberate attack or another gigantic problem resulting from excessive network centralization?
Cloudflare outage – what actually happened?
The problem occurred shortly after 12:00 Polish time. Cloudflare admitted that a configuration file designed to handle threat traffic did not work as planned and caused a crash in the traffic management system. To put it simply: one erroneous file took down a large part of the infrastructure.
We apologize to our customers and the Internet in general for letting you down
– was the company’s official statement. They also added something that should make you think:
Given the importance of Cloudflare’s services, any failure is unacceptable.
Why is this so serious?
Cloudflare is an internet security giant. Verifies that visitors are human and not bots and protects sites against DDoS attacks. The problem is that it has become one of the largest single points of failure on the network.
It’s quite amazing how many websites and portals have had to hide behind Cloudflare’s infrastructure to avoid denial-of-service attacks. However, convenience has its price and in this case it is the fragility of the entire system. Ironically, not only ChatGPT, the X portal, and Canva went down, but Downdetector itself, a portal informing about failures on the Internet.
Is this a one-time accident?
Absolutely not. Last month, Amazon Web Services installed more than 1,000 websites and applications. Shortly thereafter, similar problems affected Microsoft Azure. Jake Moore from ESET summed up the situation very well:
The failures of recent months have once again highlighted the dependence on these fragile networks.
Cloudflare shares fell about 3% shortly after 3 p.m. as the market quickly priced in the scale of the problem. The company apologized and the problem was resolved, but an uncomfortable question remains: Has the Internet become too centralized? When a handful of giants control such a huge part of the infrastructure, any mistake they make becomes a global disaster. And although there are few alternatives, perhaps this is the situation that should create them.
