Cloudflare internet service is offline again, and most websites and apps are down. This time, however, the outage was resolved within 10 minutes, in stark contrast to the November 18 disaster.
Cloudflare announced Friday that it had introduced a fix for the outage that affected its dashboard and connected apps, but did not mention the issue that caused the website to display a “500 Internal Server Error.”
The company published an update on its status page, saying it was “implementing fixes” and “monitoring system operations” while the service was back online.
The disruption caused several websites to fail, including tracking service Downdetector, social platforms LinkedIn and Substack, and centralized cryptocurrency exchange Coinbase.
Cryptopolitan has received several reports of web pages failing to load, logins being interrupted, or suddenly timing out.
Decentralized crypto platform on Solana reports failure
Several protocols on the Solana network, including Jupiter Exchange, Raydium, and Meteora, reported user interface failures during the Cloudflare outage. According to community account SolanaFloor, both platforms claimed their backends were up and running, but said customers were unable to manipulate live market information or initiate on-chain actions.
“I wanted to see if Cloudflare was down again, so I went to downdetector(.)com… Apparently Downdetector also runs on Cloudflare,” joked AI developer Pietro Montaldo.

Cloudflare published a status update at 09:38 UTC stating that its team is investigating an issue that causes a spike in empty page results when customers access the List API in the Workers KV namespace. The notice also stated that the Internet service company was investigating the cause of the problem.
Another update posted five minutes ago confirmed that engineers had “detected error levels for customers running worker scripts” and were working to analyze and contain the issue.
Cloudflare service goes down for the second time in a month
Friday’s downtime occurred after the company experienced an outage on Nov. 18 at 11:20 UTC. At this time, the global network began to fail to deliver core traffic due to a database permission malfunction.
According to an explanation outlined in a Cloudflare blog post, the unauthorized permissions required the database to generate several entries in a “capability file” used by the bot management system.
The file doubled in size, exceeding the limits supported by the routing software on the network responsible for handling large amounts of global Internet traffic, and inevitably crashed.
Engineers suspected there was some kind of cheating, but later discovered the real cause and stopped the oversized file from propagating, replacing it with the previous version and restoring normal functionality.
According to Cryptopolitan reportcore traffic was restored by 2:30 p.m., and the team then spent several hours resolving the increased load on the system as global traffic returned.
“We apologize for the impact on our customers and the internet at large. Given Cloudflare’s importance to the Internet ecosystem, any outage to our systems is unacceptable. The period in which our network was unable to route traffic has been extremely painful for all of our team members. We know we have let you down today,” Cloudflare apologized.
Several large centralized cryptocurrency platforms rely heavily on Cloudflare to stabilize their traffic loads. BitMEX reported disruptions during the outage, and blockchain services linked to Toncoin also experienced delays and downtime.
Should encryption services be withdrawn from content delivery networks?
Amazon Web Services and Cloudflare are two of the most popular content delivery networks (CDNs) that platforms, including cryptocurrency exchanges, rely on. When AWS went down in October, Infura, Coinbase’s base network and infrastructure provider that supports numerous blockchain applications, was temporarily taken offline.
According to Fadl Mantash, chief security officer at Tribe Payments, the series of failures is another reason why cryptocurrency companies should consider fully decentralizing.
“The infrastructure behind a single transaction relies on a chain of cloud platforms, processors, third-party APIs, authentication tools, and card schemes. If any link in that chain fails, the entire process can be disrupted,” Mantash pointed out.
The blockchain itself may continue to process transactions, but if Cloudflare or AWS is interrupted, traders will not be able to see any activity or interact with their assets.
