A major fire at a data center in the Milan metropolitan area early this morning knocked out internet and cloud services for thousands of users and disrupted business operations across the region.
What happened
Technicians say an equipment fault sparked a blaze inside electrical cabinets, which quickly damaged power and cooling infrastructure in the facility. Emergency crews contained the fire within hours, preventing it from spreading to neighboring sites, but the site itself suffered significant equipment loss.
Immediate impact
Multiple telecom carriers reported degraded connectivity and interruptions to both consumer broadband and corporate networks. Several cloud-hosted services experienced downtime, and small and medium-sized businesses reported slowdowns or temporary loss of access to hosted applications. Mobile networks also felt the strain: backbone congestion and rerouting produced sporadic service issues for cellular users.
How operators responded
Data center engineers isolated affected racks and activated failover procedures, shifting workloads to backup systems in other facilities where possible. Network operators implemented reroutes and traffic-shaping to ease congestion, and temporary power and cooling solutions were deployed to support critical systems. Providers prioritized restoration for hospitals, emergency services and other essential customers, and many clients switched to backup links or alternate cloud regions.
Investigation and recovery
Authorities have opened an investigation into the electrical cabinet failure; police told reporters they are reviewing recent maintenance records and work orders. Forensic teams are due to release an initial technical update later today. Restoration is underway but conditional on power availability and part replacements—officials estimate a phased recovery, with partial connectivity possible within 24 to 72 hours, though final timelines remain tentative.
What to expect next
Engineers continue on-site assessments, repairs and safety checks before systems are fully reconnected. Service providers and regulators say they will publish further updates as repairs progress and more information from the investigation becomes available. If you rely on hosted services in the Milan area, check your provider’s status page and follow recommended contingency steps while networks are restored.
