Centurylink internet outages: What is current status? 1000s across US report internet outage
A widespread internet outage disrupted telecommunications across the United States on June 19, with more than 45,000 users losing access to broadband services.
The disruption was particularly severe in Colorado, where local users of Quantum Fiber and other providers experienced major connectivity issues.
The outage affected several major providers, including CenturyLink, Quantum Fiber and Brightspeed, and lasted for over two and a half hours, making it one of the most significant broadband failures in recent months.
Outage tracking data from platforms such as Down Detector indicated that over 35,000 CenturyLink customers were impacted nationwide.

Quantum Fiber, a fibre-based broadband service widely used in Colorado, saw more than 17,000 reports. Brightspeed, a smaller regional operator, also reported in excess of 3,000 service issues during the same period.
Reports of outages came from multiple states, suggesting the issue was not confined to one region.
Users described full connectivity loss, sluggish browsing speeds, and intermittent service drops throughout the day. Colorado residents, especially in the Denver metropolitan area, appeared to be among the hardest hit.
As of Thursday evening, none of the affected companies had issued detailed statements clarifying the underlying cause of the outage.

The silence has prompted further frustration among customers, many of whom took to social media and internet forums to seek explanations and workarounds.
CenturyLink and Quantum Fiber are both operated under Lumen Technologies, which manages legacy copper networks and newer fibre infrastructure.
Brightspeed, once part of Lumen's coverage area, now operates independently across 20 US states.
@Centurylink is down nationwide and they refuse to make a post about it. A simple 'we are experiencing a nationwide outage and currently resolving it' would be nice, but they're not saying anything about it. — EDEN (@ColdGoldWorld) June 19, 2025
Though service was largely restored by mid-afternoon, the incident sparked concern about the stability of national broadband infrastructure. With more businesses, schools and essential services relying on uninterrupted internet access, such outages have significant implications.
The disruption also reignited discussion around ownership transitions and service delivery models within the US telecommunications sector. Industry analysts say infrastructure consolidation — such as the recent Quantum Fiber acquisition — often brings both investment and operational complexities.
Authorities have not confirmed whether the outage was caused by technical failure, maintenance error, or an external threat. Customers affected are advised to check directly with providers for any potential compensation or follow-up support.

AI and the environment
The writer is an academic and researcher. He is also the author of Development, Poverty, and Power in Pakistan, available from Routledge Listen to article For Gen X people like me, who are trying to get used to the new world of AI, like we learnt using the computer, and then the Internet many years ago, it is intriguing to see how AI is becoming integrated into our lives. For researchers like me, AI is making it easier to navigate Internet searches, and to synthesise relevant literature. Besides such novice applications of AI, however, this evolving technology is going to start playing an increasingly prominent role in more salient aspects of our lives ranging from healthcare, education, manufacturing, agriculture, and even warfare. There are also legitimate reasons to be wary of AI's power. AI is making it much easier to spread disinformation, enable fraud, and cause conflicts to become deadlier. Moreover, AI, like many other technologies that we have become so dependent on in our consumerist world, ranging from cars to cell phone, has significant environmental impacts. This heavy ecological footprint of AI is more concerning to me than speculations about AI dominating or replacing humans. AI has a much larger environmental impact than many of the other innovations we now depend on, due to the exorbitant amount of energy needed to operate and train AI systems, and because of the e-waste produced by the hardware used to run AI. Training and operationalising large language models such as ChatGPT depend on energy still being generated via fossil fuels, which is leading to more carbon emissions, and increased global warming. Each ChatGPT question is estimated to use around 10 times more electricity than a traditional Google search. Producing and disposing of AI hardware also generates a lot of e-waste comprised of harmful chemicals. Running AI models need a lot of water too, to cool the data centres which house massive servers, and to cool thermoelectric or hydroelectric plants which supply electricity for these data centers. The race to produce AI is also compelling major tech giants to walk back on their earlier environmental pledges. Consider, for instance, the case of Google. A few years ago, Google set an ambitious target to address climate change by becoming 'net zero' emissions, but now the company's emissions are growing due to Goggle's bid to become a leader in AI. As the AI industry continues to grow, its environmental impact will grow too. However, as is the case of ecological destruction caused by over consumption of other products, the environmental impacts of AI will not be evenly distributed across different regions or socio-economic classes. The benefits of AI will not be evenly spread either. Higher income countries are better poised to capture economic value from AI because they already have better digital infrastructure, more AI development resources, and advanced data systems. Better off households will be able to enjoy the benefits of AI, while having more resilience in terms of shielding themselves from its adverse impacts. Conversely, the quest to produce more AI may cause exploitation in poorer countries that provide the critical resources needed for AI. This is not a speculative statement, but one based on ground realities. Consider, for instance, the dismal condition of miners, including children, in poor African countries like Congo, who are toiling away to produce cobalt to power batteries used to run electric cars, and our phones. Al will require many more of these critical resources, potentially leading to even more exploitation of people and natural environments in resource-rich but poor countries. It is important to improve the energy efficiency of AI models and data centers, and to use renewable energy sources to power AI data centres. Moreover, it is also vital to promote more sustainable mining and manufacturing practices and improve e-waste management to reduce the amount of harmful chemicals entering the environment. However, whether these efforts will be paid more attention than maximising profits within this highly unregulated new domain of human innovation remains to be seen.

Is ChatGPT still down? OpenAI gives clarification after significant global outage reported
OpenAI's popular chatbot, ChatGPT, experienced significant disruptions on June 10, following a partial system failure that also affected its video tool, Sora, and its developer interface. The service outages began early on Tuesday morning, with Downdetector, a platform tracking outages, noting a sharp spike in user complaints shortly after 5:30 a.m. At the peak, nearly 2,000 reports were logged from users facing errors and access issues. OpenAI confirmed the issue and initiated an investigation. By midday, the company reported signs of recovery for both ChatGPT and its API platform, although engineers warned that a full resolution could take several hours. Performance varied throughout the day, with some users intermittently able to access the service. In a post on social media platform X, OpenAI acknowledged the 'elevated error rates and latency' and assured users that the root cause of the problem had been identified. "We are working as fast as possible to restore normal operations," the company said. We are observing elevated error rates and latency across ChatGPT and the API. Our engineers have identified the root cause and are working as fast as possible to fix the issue. For updates see our status page: — OpenAI (@OpenAI) June 10, 2025 The outage underscores ChatGPT's deep integration into daily tasks. According to data from HR Dive, workplace usage of the tool has doubled over the past year, while a Pew Research survey revealed that over 25% of US teenagers now rely on ChatGPT for academic support—double the figure from 2023. This incident adds to a growing list of disruptions affecting major digital platforms this year, including Zoom and X, further highlighting the challenges faced by organisations relying on such tools for productivity. OpenAI continued to work on resolving the issue, with technicians monitoring the situation through the night. By the early hours of June 11, the company reported that full recovery had been achieved for most users, though voice mode remained affected by increased error rates.
