Network Failover

Anticipating and addressing network failure is crucial to enterprise operations

A stressed worker looking into a server room trying to figure out why there was a network failure.

Network failure is potentially devastating in today’s era of technology-driven businesses. With so much network reliance, failures, or even interruptions can cost enterprises dearly in money, reputation, and time. To effectively anticipate, avoid, and address this issue, businesses need to understand the:

  • Complexities of network systems
  • Causes and impacts of network failures
  • Cost-effective solutions available

Causes of network failure

Understanding how network failures happen is the first step in avoiding and addressing them. Some of the most common causes include:

  • Software failures
  • Hardware failures
  • Misconfiguration or errors in network setup
  • Power outages
  • Human Error
  • Network congestion

Unforeseen circumstances

Unforeseen circumstances, such as natural disasters, power outages, and network-wide disruptions, can temporarily or indefinitely disrupt networks. As such, businesses must implement measures that will enable them to remain running during such events. Data centers, redundant network devices & systems, and regular testing of system functionality will help businesses avoid shutdowns and address them quickly when they do happen.

Congestion and overload

Congestion and overload can severely affect network performance. In most cases, the issues are caused by the misconfiguration of routers or parameters that govern traffic flow. Relieving these issues requires a thorough evaluation of the system and its parameters. Installing load balancers will evenly distribute traffic across multiple devices and reduce the strain on individual components.

Network misconfiguration

The misconfiguration of network components is one of the most common causes of network failure. This includes improper setup of routing tables, incorrect parameter settings, and device configuration errors. To ensure the proper functioning of a network, system administrators must be able to identify and troubleshoot any configuration changes or network issues that arise.

Security breaches

Hackers and malicious actors can easily exploit security vulnerabilities, leading to a loss of confidential information, data corruption, and other financial losses. Businesses must implement security measures such as firewalls, regular virus scans, and authentication processes to protect their networks.

Software failures

Software errors or badly configured systems, including hardware compatibility issues and configuration conflicts, can impede network functions. Regular updates of software and hardware help minimize this risk. Additionally, rigorous testing of system functionality should be conducted to identify and resolve any potential issues.

Bugs in the firmware

Bugs in the firmware can lead to sudden network failure. Regular firmware updates help prevent the introduction of bugs. Businesses should also test new firmware versions before they are implemented.

Network topology conflicts

Conflicts between network topologies can also lead to network failure. This can include IP address conflicts, incorrect routing, and improper cabling. Proper cabling and continual monitoring of networks is essential to ensure conflicts do not arise.

Hardware failures

Hardware failures are a significant concern as well, as a defective or broken device can cause system-wide malfunctions. To reduce the risk of hardware failure, businesses must regularly replace obsolete equipment and test all devices before implementation.


Firewalls are essential for protecting networks from unauthorized access and malicious actors, both at the hardware and software level. However, they can also fail due to improper implementation, incorrectly configured software, and a lack of security patches. Deploying updated versions of the software as it becomes available and regularly performing security scans helps mitigate this risk.


Discontinuities in power supplies, cables, routers, and other network equipment can also cause network failure. This is best mitigated with regular inspection and replacement of defective equipment.

Power failure

Power supplies are essential for the operation of most network systems, and interruptions in power have a proportionate impact on networks. Businesses must ensure that their power supplies are correctly configured and functioning properly. Installing surge protectors is one way to prevent network interruption or failure from power surges caused by shorts or electrical storms.

Reducing risk of network failure

To reduce the risk of network failure, businesses must proactively monitor and troubleshoot their systems. Cost-effective solutions such as load balancers, failover solutions, and parameter monitoring can help prevent network downtime. Additionally, enterprises can rely on some of the best practices for reducing the risk of network failure, which include:

  • Regular system troubleshooting
  • Anticipating potential issues
  • Monitoring performance
  • Improving network security

Regular system testing

Periodic testing is essential for ensuring network stability. These tests must evaluate the functionality of the system, detect any issues, and identify misconfigurations, and should be conducted on a regular basis.

Anticipating issues

Solutions should not be determined when a network issue happens, but in advance. Businesses must be prepared to respond to potential issues quickly and efficiently. To ensure this, system administrators should be trained to anticipate and troubleshoot any potential issues that may arise.

Active performance monitoring

Monitoring performance allows businesses to identify any potential issues before they result in network outages. Network management systems can be used to provide insight into system operations and track the performance of different devices and routers.

Improving network security

One of the most important aspects of network security is patch management. Regularly applying security patches to devices and systems can help protect networks from malicious actors and protect data from potential breaches. Additionally, businesses must regularly scan for potential vulnerabilities and apply appropriate measures to protect their systems.
