Cloudflare Explains Major Service Outage: Not a Security Breach, No Data Lost

 

Cloudflare has clarified that a widespread outage affecting its global services was not the result of a cyberattack or data breach. The company confirmed that no customer data was compromised during the disruption, which significantly impacted numerous platforms, including major edge computing services and some Google Cloud infrastructure. 

The issue began at approximately 17:52 UTC and was primarily caused by a complete failure of Workers KV, Cloudflare’s globally distributed key-value storage system. As a backbone for its serverless computing platform, Workers KV plays a crucial role in supporting configuration, identity management, and content delivery across many of Cloudflare’s offerings. When it went offline, critical functions across the ecosystem were immediately affected. 

In a post-incident analysis, Cloudflare revealed that the root cause was a malfunction in the storage infrastructure that underpins Workers KV. This backend is partially hosted by a third-party cloud service, which experienced its own outage—directly leading to the failure of the KV system. The ripple effects were far-reaching, disrupting Cloudflare services for nearly two and a half hours. 

Key services impacted included authentication platforms like Access and Gateway, which saw major breakdowns in login systems, session handling, and policy enforcement. Cloudflare’s WARP service was unable to register new devices, while Gateway experienced failures in DNS-over-HTTPS queries. CAPTCHA and login tools such as Turnstile and Challenges also malfunctioned, with a temporary kill switch introducing token reuse risks.  
Media services like Stream and Images were hit particularly hard, with all live streaming and media uploads failing during the incident. Other offerings such as Workers AI, Pages, and the AutoRAG AI system were rendered entirely unavailable. Even backend systems like Durable Objects, D1 databases, and Queues registered elevated error rates or became completely unresponsive.  

Cloudflare’s response plan now includes a significant architectural shift. The company will begin migrating Workers KV from its current third-party dependency to its in-house R2 object storage solution. This move is designed to reduce reliance on external providers and improve the overall resilience of Cloudflare’s services. 

In addition, Cloudflare will implement a series of safeguards to mitigate cascading failures in future outages. This includes new cross-service protections and controlled service restoration tools that will help stabilize systems more gradually and prevent sudden traffic overloads. 

While the outage was severe, Cloudflare’s transparency and swift action to redesign its infrastructure aim to minimize similar disruptions in the future and reinforce trust in its platform.

Casio Hit by Cyberattack Causing Service Disruption Amid Financial Challenges

 

Japanese tech giant Casio recently experienced a cyberattack on October 5, when an unauthorized individual accessed its internal networks, leading to disruptions in some of its services.

The breach was confirmed by Casio Computer, the parent company behind the iconic Casio brand, recognized for its watches, calculators, musical instruments, cameras, and other electronic products.

"Casio Computer Co., Ltd. has confirmed that on October 5, its network was accessed by an unauthorized third party," the company revealed in a statement today. Following an internal review, the company discovered the unauthorized access led to system disruptions, which have caused some services to be temporarily unavailable. Casio mentioned it cannot provide further details at this stage, as investigations are still ongoing. The company is working closely with external specialists to assess whether personal data or confidential information was compromised during the attack.

Although the breach has disrupted services, Casio has yet to specify which services have been impacted.

The company reported the cyber incident to the relevant data protection authorities and quickly implemented measures to prevent further unauthorized access. BleepingComputer reached out to Casio for more information, but a response has not yet been provided.

So far, no ransomware group has claimed responsibility for the attack on Casio.

This attack comes nearly a year after a previous data breach involving Casio's ClassPad education platform, which exposed customer data from 149 countries, including names, email addresses, and other personal information.

The recent cyberattack adds to the company's challenges, as Casio recently informed shareholders of an expected $50 million financial loss due to significant personnel restructuring.

Flight Data Issues Trigger UK Air Traffic Control Failure

 

A significant air traffic control malfunction resulted in extensive flight disruptions, leaving numerous passengers stranded both domestically and internationally. The root cause of this disruption was attributed to issues with the reception of flight data.

Martin Rolfe, the CEO of National Air Traffic Services (Nats), disclosed that the primary and backup systems experienced a suspension of automatic processing during the incident. In his statement, Mr. Rolfe clarified that there is no evidence to suggest that the malfunction was the result of a cyber-attack.

Furthermore, Mr. Rolfe sought to provide assurance by emphasizing that all Nats systems have been operating normally since Monday afternoon, effectively supporting the seamless functioning of airlines and airports.

He said: ‘Very occasionally technical issues occur that are complex and take longer to resolve.  In the event of such an issue our systems are designed to isolate the problem and prioritise continued safe air traffic control. This is what happened yesterday. At no point was UK airspace closed but the number of flights was significantly reduced. Initial investigations into the problem show it relates to some of the flight data we received.'

‘Our systems, both primary and the back-ups, responded by suspending automatic processing to ensure that no incorrect safety-related information could be presented to an air traffic controller or impact the rest of the air traffic system.'

The trouble began on Monday when over 25% of flights at UK airports faced cancellations.

Nats encountered what they labeled as a 'technical glitch,' rendering them unable to automatically process flight plans. Consequently, flights to and from UK airports were subject to restrictions while manual checks were conducted on these plans.

Although Nats reported the issue resolved at 3.15 pm on Monday, the disruption persisted into Tuesday due to aircraft and crews being displaced.

An analysis of flight data websites conducted by the PA news agency revealed that on Tuesday, a minimum of 281 flights, encompassing both departures and arrivals, were canceled at the UK's six busiest airports. Specifically, there were 75 cancellations at Gatwick, 74 at Heathrow, 63 at Manchester, 28 at Stansted, 23 at Luton, and 18 at Edinburgh.

In response to the air traffic control malfunction, EasyJet announced its plans to operate five repatriation flights to Gatwick and deploy larger aircraft on crucial routes.

It said: ‘During this traditionally very busy week for travel, options for returning to the UK are more limited on some routes and so easyJet will be operating five repatriation flights to London Gatwick over the coming days from Palma and Faro on August 30, and Tenerife and Enfidha on August 31 and from Rhodes on September 1.

‘We are also operating larger aircraft on key routes including Faro, Ibiza, Dalaman and Tenerife to provide some additional 700 seats this week.’
