Thousands of residents and businesses in London have been affected by a major broadband outage impacting Community Fibre customers. The disruption began around midday (GMT), quickly spreading across the city, making it one of the most significant outages in recent memory.
London’s Community Fibre Faces Widespread DNS Outage, Leaving Customers Frustrated
On February 17, 2025, a major internet outage affected Community Fibre customers across London, caused by a DNS problem. Users found that changing their DNS settings to public servers like Cloudflare’s 1.1.1.1 or Google’s 8.8.8.8 fixed the issue. The outage caused a lot of frustration as people couldn’t reach Community Fibre’s customer service—phone lines were busy, live chat didn’t work, and users had trouble accessing their accounts. Since there was no official explanation from Community Fibre, people speculated that the problem might have been caused by hacking or technical failures.
The Extent of the Outage
The outage has affected various areas throughout London, with over 9,000 complaints reported on Downdetector. From southeast to northwest London, users have struggled with internet connectivity, leaving many frustrated. Community Fibre, which serves over 1.3 million homes and 185,000 businesses, has found itself in the middle of this crisis.
Challenges for Customers
Social media, especially X (formerly Twitter), became the main platform for customers to express their frustration. Many reported not just internet disruptions but also issues reaching customer support. Live chat services were down, phone lines were unresponsive, and the service status page was inaccessible, leaving users uncertain about when the issue would be fixed.
Possible Causes of the Outage
Although Community Fibre has yet to confirm the cause, there is speculation that the outage could be due to a cyber attack or an infrastructure failure. Some users suggested a potential workaround by switching to Google’s public DNS settings, which seemed to help temporarily. However, this fix didn’t work for everyone, and many remained without service.
Community Fibre’s Response
Once the company’s website became accessible again, Community Fibre issued an official statement, acknowledging the problem and calling it a “high priority” issue. They assured customers that their engineers were working hard to resolve the disruption. While they apologized for the inconvenience, the lack of communication on social media during the outage has drawn criticism from users.
Impact on Daily Life
The timing of the outage couldn’t have been worse. It came at a time when many people rely on the internet for work, online learning, and entertainment. Businesses, in particular, were severely affected, as many depend on stable internet for transactions, communications, and daily operations. This situation highlighted how vital reliable internet service is to the modern lifestyle, especially in a tech-driven city like London.
What Happens Next?
As of the latest update at 7:07 PM IST (1:37 PM GMT), there is no confirmed timeline for full service restoration. While Community Fibre has promised updates, many Londoners are turning to mobile data or adjusting their plans as they await a solution. The outage has sparked discussions about internet infrastructure resilience and the need for better communication from service providers during such events. Many are also exploring alternative internet options or backup solutions.
