Yes, internet outages are sometimes directly caused by security breaches at major providers, not equipment failures. Rather than a single recent "community" incident, the verified research shows a pattern: between 2024 and 2026, multiple ISPs worldwide suffered significant outages after attackers compromised their systems, ranging from credential theft to destructive server wipes.
The most dramatic example is the Russian ISP Nodex, which suffered complete network destruction on January 6–7, 2025, after Ukrainian Cyber Alliance hackers breached its systems and deleted internal servers, causing customer internet traffic to drop to zero. More common are targeted account hijackings: Orange Spain experienced a three-hour regional outage on January 3, 2024, after a hacker stole employee credentials and misconfigured the company's routing protocols. These incidents reveal how a single security failure at a provider can cut off internet access for hundreds of thousands of customers.

How Attackers Shut Down Internet Service
Security-caused outages typically follow one of two paths. The first is account hijacking: at Orange Spain, attackers used credentials stolen by Raccoon malware to access the company's RIPE account—a control system for internet routing—then misconfigured Border Gateway Protocol settings, causing 50% traffic loss across the region. This requires no physical access and can be executed from anywhere online in minutes once credentials are compromised.
The second path is destructive server wipe. Nodex attackers exfiltrated sensitive data before systematically destroying the ISP's internal infrastructure, forcing recovery from backups and taking multiple days to restore service. Smaller-scale versions appear in municipal systems: University City, Missouri's monthlong outage of online bill payments and building permits was caused by a cyberattack rather than equipment failure, though the full attack method was not disclosed publicly.
Recent Major Incidents and Their Scale
The Nodex attack in January 2025 caused complete traffic loss for an unknown number of Russian residential and business customers as Ukrainian Cyber Alliance hackers confirmed their role and published screenshots from compromised internal systems. The attackers were motivated by Russia's invasion of Ukraine and treated the ISP as a legitimate military-adjacent target.
Orange Spain's hijacking in 2024 affected 50% of the company's customer traffic, according to Cloudflare monitoring, but recovery took only three hours once staff detected and reversed the routing misconfiguration. More recent data breaches at ISPs—including a multi-provider breach exposing 14.2 million login credentials in January 2026 and Brightspeed's exposure of 1+ million customers' names, addresses, and payment data in the same month—have not resulted in confirmed widespread outages, though threat actors have claimed (without verification) to have disconnected service.
Who Is Affected and How Long Outages Last
security-caused outages affect not just internet users but businesses, hospitals, schools, and government services that depend on continuous connectivity. Orange Spain's three-hour outage disrupted regional commerce and communications, while Nodex's destruction lasted multiple days as engineers restored systems from backups.
The recovery time depends on whether the attack is reversible (routing misconfiguration: minutes to hours) or destructive (server wipe: days). Small municipalities like University City face particular risk because they often run older systems with limited security staff, and the monthlong outage of city services showed how a single attack can paralyze essential functions like permit processing and utility bill payments. Residential customers may not even know an outage was caused by a breach rather than weather or equipment failure.
How These Differ from Routine Outages
Most internet outages result from weather, fiber cuts, power failures, or hardware malfunctions—not deliberate attack. A June 2026 industry report tracked 516 network outage events globally in a single week, with a 26% surge compared to the previous week, but most were attributed to infrastructure failures, weather, and power disruptions rather than security incidents. This means security-caused outages remain the exception, not the norm.
The distinction matters for recovery. With a hardware failure, a provider replaces equipment or reroutes traffic. With account hijacking, they must change passwords and verify no persistent backdoors exist before full restoration. With server wipes like Nodex's, they must rebuild systems from scratch or offline backups, a process that can take days and carries risk of data loss.
What Providers and Customers Should Know
For ISPs and hosting providers, the Nodex and Orange Spain incidents underscore the critical importance of multifactor authentication on administrative accounts and real-time monitoring of routing and server configuration changes. The Raccoon malware that stole Orange Spain's credentials is a common credential stealer still in circulation, making employee password security and endpoint detection essential.
For customers, outages caused by breaches are largely outside individual control but awareness helps you understand timelines. If your ISP announces an outage caused by a cyberattack, expect either a quick recovery (if it's routing-based like Orange Spain) or a prolonged one (if servers were damaged). If you suspect a breach caused your outage, contact your provider to confirm and ask whether your personal data was exposed—the two are not always connected.
Frequently Asked Questions
Can attackers really knock out an entire ISP's internet service?
Yes. Nodex experienced complete traffic loss after a destructive server wipe, and Orange Spain lost 50% of customer traffic through routing hijacking. Both required the attacker to gain administrative access to critical systems.
How do hackers get ISP login credentials?
Common methods include malware like Raccoon that runs on employee computers, phishing emails targeting staff, or purchasing stolen credentials from previous breaches. Orange Spain's attacker used Raccoon credentials from September 2023 to strike four months later.
How can I know if an outage was caused by a security breach?
Your ISP should disclose the cause publicly within hours or days. Security-caused outages are relatively rare and newsworthy, so major incidents typically appear in industry coverage. You can also ask your provider's support team directly.
Does a data breach always cause an outage?
No. Most ISP and hosting breaches steal data but do not disrupt service. Brightspeed's 2026 breach exposed millions of customers' personal information without confirmed outages, though attackers claimed to have disconnected service.
