Proximus experienced a second internet disruption this week, impacting both fixed-line and mobile services, the company confirmed. The latest incident, affecting fixed internet connections, occurred between 11:00 and 13:00 on Thursday, March 19, 2026, and was fully resolved by 14:00, according to a company spokesperson.
A local business owner reported disruptions to their Point of Sale system during the outage
Technical Issue Identified
The disruption to fixed-line internet service was traced to a faulty router within Proximus’s central infrastructure. “The technicians were able to quickly identify the source of the problem. It was a defective router that created a surge,” explained Haroun Fenaux.
users experienced reduced network capacity. “It wasn’t a complete outage, but service was limited. Some people could connect, others could not,” Fenaux added.
Several businesses reported issues with connectivity, particularly with payment terminals. Service began to return to normal in the early afternoon. “From 13:00 to 14:00, connectivity was able to return to normal,” Fenaux stated. Customers still experiencing issues are advised to restart their modems.
A significant mobile network outage impacted Proximus customers on Monday
Impact on Multiple Operators
The disruptions extended beyond Proximus’s direct customer base. “Scarlett and Mobile Vikings were similarly affected,” Fenaux noted, due to their reliance on Proximus’s network infrastructure.
The mobile outage on Monday similarly impacted users on other networks. Any customer utilizing the Proximus network, including those of operators like DIGI, who currently leverages Proximus for its mobile subscriptions while expanding its own network, experienced service interruptions.
Company Downplays Connection Between Incidents
Proximus maintains that the two incidents are unrelated. “These are two extremely rare problems that happened in the same week,” Fenaux reiterated.
The company sought to reassure customers that it is taking steps to prevent future disruptions. “Zero risk doesn’t exist, but we are doing everything we can to prevent this from happening,” Fenaux said.
When questioned about the possibility of sabotage or a cyberattack, Fenaux stated, “Nothing indicates that. These are technical problems not related to sabotage or a cyberattack.”
