According to the Uptime Institute, network and connectivity issues are the leading cause of IT service outages, ahead of power and software failures. Yet most companies focus on backups and servers in their business continuity planning, while their entire operation quietly depends on a single cable for internet access. Here’s why network redundancy belongs in every continuity plan, what independent routes and multiple providers involve, and why a carrier-neutral data center makes sense.
Most business continuity plans are built around the server room: redundant power supplies, mirrored storage, and tested backup recovery. Connectivity to the outside world often appears as a single line item labeled “internet,” with just one provider listed. Let’s first look at what happens when that link in the chain breaks.
Servers Survive, Business Stops: A Blind Spot in Business Continuity Planning
Perfectly protected infrastructure without network connectivity is like a bank with a full vault but doors welded shut. Everything inside is safe, but nobody can get to it. That’s how customers and employees experience a network outage: servers report 100% uptime while the business is unreachable. The effects emerge within minutes:
- Customer-facing services – VoIP calling, online stores and payment terminals stop responding; customers leave before IT finds the cause.
- Cloud applications – CRM, ERP and email still work, but employees cannot access them outside the office.
- Branch operations – Warehouses, stores and production lines lose their connection to central systems and stop.
- Internal systems – Time tracking, access cards and manufacturing controls dependent on remote authentication enter emergency mode.
None of this requires a failed disk or a flooded server room. One careless excavator near a fiber-optic cable, a faulty edge router or a provider error will do. A plan covering only server recovery offers no solution.
Where Network Connectivity Breaks Down
The figures show this is no minor risk. As noted earlier, a 2026 Uptime Institute survey found that network and connectivity issues accounted for 23% of IT service outages, ahead of power failures (21%) and software failures (18%). Incidents involving fiber-optic routes more than doubled compared with the 2020–2025 average, while publicly reported telecom provider outages rose from 29 in 2020 to 39 in 2025.
According to the same survey, network outages have three leading causes:
- Configuration and change management errors
- Third-party provider failures
- Hardware failures
Two are wholly or partly beyond a company’s control. The first, however, is internal, and adding a second cable won’t solve it. As more business systems move to the cloud or are delivered as services, every application now depends on a connection to the outside world. The more distributed the infrastructure becomes, the more critical the links holding it together.
Network Redundancy Means More Than a Second Cable From the Same Provider
True backup connectivity starts with physical separation. Two fiber-optic routes must enter the building from different sides and follow different streets; otherwise, one excavator could sever both. A second connection from the same provider protects against a cut cable, but not a failure in its backbone network. That’s why a continuity plan needs two independent providers. Automatic failover, often managed through SD-WAN, monitors connection quality and reroutes traffic before users notice an interruption. LTE or 5G backup adds another layer of protection for branch offices.
None of these safeguards matter unless tested. Outages should be simulated regularly: unplug a cable, disconnect a provider and measure how many seconds recovery takes. Since configuration errors are among the leading causes of outages, testing should follow every network change.
Carrier-Neutral Data Center: A Hub, Not a Dead End
A private server room typically has fiber connections from just one or two carriers. Adding another can take months. A carrier-neutral data center reverses that model. Its operator sells neither telecom nor cloud services, so it brings providers under one roof and establishes new connections through on-site cross-connects within days. Prague’s TTC Teleport (ttc-teleport.com) holds Uptime Institute Tier III certification and guarantees 99.982% availability, with redundant power, cooling and connectivity. It hosts major carriers and the NIX.cz peering exchange, carrying roughly 60% of Czech internet traffic. For business continuity planning, changing providers becomes a routine scheduling task instead of a construction project.
One Question for Your Next Meeting
Next time you review your continuity plan, ask how many independent routes connect your business to customers if the primary one fails. If the answer is “one,” you have a server recovery plan, not a business continuity plan. Customers will notice the difference in the first minute of an outage.
Conclusion
Business continuity is about keeping your entire business operational, not just protecting servers, data, and power supplies. Without reliable network redundancy, even the most advanced backup systems cannot prevent costly downtime when connectivity fails. Independent fiber routes, multiple internet service providers, automatic failover, and regular recovery testing are essential to maintaining uninterrupted operations. A carrier-neutral data center can make these safeguards easier to implement by providing access to multiple carriers and reliable connectivity infrastructure. Ultimately, investing in network redundancy is not just an IT decision; it is a business strategy that protects revenue, customer trust, productivity, and long-term stability. Make sure your next business continuity review covers not only what happens when your servers fail, but also what happens when your network goes down.
