This past Monday, many businesses and individuals across the country were impacted by a large-scale network outage. It served as a reminder that even the most robust networks can experience downtime. While large telecom providers and service operators often invest millions in complex redundancy systems, the reality is that even small-to-medium-sized businesses can mitigate the impact of such outages without breaking the bank.
The key? Redundancy. And contrary to popular belief, redundancy doesn't have to be expensive.
Why Redundancy Matters
In our increasingly connected world, businesses rely heavily on constant network access for everything from cloud applications to communications, and even brief outages can result in lost productivity, missed opportunities, and unhappy customers. When a major provider suffers an unexpected outage, the businesses that have no redundancy in place are forced to simply wait until services are restored. Those that have planned ahead, however, can often switch over to a backup connection seamlessly, minimizing or completely avoiding downtime.
Types of Network Redundancy
Network redundancy comes in many forms, and a robust failover system can be customized based on the size and needs of the organization. Here are a few options that can fit a wide range of budgets:
1. Dual Internet Connections
One of the simplest and most cost-effective forms of redundancy is to have multiple internet service providers (ISPs). If your primary provider goes down, your router can automatically switch to the secondary provider.
For businesses in areas with only one major provider, options like 4G LTE or 5G cellular connections can act as affordable and reliable backups. Many enterprise-grade routers can seamlessly switch to these connections when needed. Devices such as dual-WAN routers are widely available and relatively inexpensive, allowing you to connect to two ISPs at once.
Cost: This type of redundancy can be surprisingly affordable. Many businesses can obtain a basic second connection or a 4G LTE backup plan for under $100 per month.
2. Cloud-Based Failover Solutions
Many cloud services offer redundancy features as part of their infrastructure. For businesses heavily reliant on cloud services, having multi-region availability through cloud providers can ensure that your systems stay online even if a specific region experiences network issues.
Additionally, leveraging SD-WAN (Software-Defined Wide Area Network) technology can help businesses manage multiple connections and route traffic based on performance. SD-WAN solutions prioritize traffic through the best-performing connections, switching seamlessly when an outage occurs.
Cost: While traditional WAN solutions are often expensive, many SD-WAN solutions are now offered as managed services or pay-as-you-go options, making them affordable for smaller businesses.
3. Local Network Redundancy
It’s important to remember that redundancy isn't just about your internet connection. Local network failures, such as hardware malfunctions, can also cause outages. Building redundancy into your internal infrastructure—such as redundant switches, routers, and firewalls—can minimize internal network disruptions. Equipment like uninterruptible power supplies (UPS) can keep your critical network hardware running in case of power outages.
Many network devices now come with dual power supplies or other built-in redundancy features. While enterprise-grade equipment can be expensive, there are many affordable alternatives that offer high reliability and basic redundancy features.
Cost: Investing in mid-range network devices with built-in failover features is more affordable than it seems. For instance, routers and switches with dual power supplies or passive/active failover options can be found for under $500.
4. Automatic Failover and Monitoring
Simply having a secondary connection isn’t enough—you need a way for your system to know when to switch over. Fortunately, many modern routers and firewalls come with automatic failover capabilities. These devices can continuously monitor the health of your primary connection and automatically switch to the backup connection in the event of an outage.
Cost: Many consumer and SMB-grade routers include automatic failover features, and free or low-cost network monitoring tools make it affordable to maintain awareness of your network’s health.
Benefits of Network Redundancy
While network outages are frustrating, they don't have to cripple your business. Implementing redundancy in your network brings several advantages:
-
Minimized Downtime: With automatic failover systems in place, businesses can continue operating even during a major outage. The switch to backup connections can be seamless and immediate.
-
Customer Trust: For customer-facing applications or websites, continuity is crucial. Redundancy prevents outages from affecting your reputation and helps maintain customer trust.
-
Increased Productivity: Employees remain productive and online, even when the primary connection fails. A redundant network ensures that crucial communication and collaboration tools remain available.
Conclusion: Affordable Redundancy is Possible
While large network operators invest heavily in redundancy, smaller organizations can implement highly effective solutions at a fraction of the cost. Redundancy doesn’t need to mean a complete duplication of everything—targeted, well-thought-out measures like a secondary internet connection, SD-WAN, or affordable automatic failover features can keep your business online when it matters most.
Monday’s outage was a reminder that disruptions can happen to even the largest and most sophisticated networks. Businesses that take steps now to implement redundancy will be better positioned to keep running smoothly the next time a disruption occurs—no matter what happens upstream.
