Your entire business runs on internet connectivity. Everything from customer transactions and internal communications to cloud apps and remote work depends on your network – and when connectivity fails, the consequences are enormous.
According to Splunk’s "Hidden Costs of Downtime 2026" report, companies lose an average of $300 million each year to unplanned outages.1 That’s millions in lost productivity, missed opportunities, and damaged customer relationships, making network reliability one of the most important factors in operational success.
But what exactly is network reliability, and what can you do to improve it? In this guide, explore the tools and metrics that matter for building a more reliable network infrastructure for your organization.
Network reliability is your network infrastructure's ability to perform functions without failures or performance degradation. A reliable network should be able to maintain stable connectivity and minimal downtime across all conditions – during peak usage hours, periods of high demand, or when individual components experience issues.
Reliability isn’t the same as availability, though the terms are often confused. Availability measures uptime, which refers to whether your network is operational. Reliability measures the quality of that operation (speed, latency, packet loss) and the ability to maintain service quality under various conditions.
Network reliability affects every digital operation your business runs. When networks aren't reliable, your team's productivity takes a hit due to issues such as dropped video calls, cloud applications timing out, or failed file transfers.
The financial impact should get your attention. The average cost of downtime now exceeds $14,000 per minute for midsize businesses.2 But beyond the direct financial hit, unreliable networks can damage customer trust and tank employee satisfaction.

Getting network reliability right requires tracking the metrics that actually matter. Here are the ones you should know about:
Understanding these network reliability metrics can help you figure out where to invest in improvements and which areas will have the biggest impact on your operations.
Knowing how to test network reliability is helpful for catching problems before they impact operations. Here are the basics:
Set up automated monitoring that runs 24/7 and tracks your key metrics. This gives you historical data to spot trends and alerts you to problems as they develop – before they become full-blown failures.
Run regular speed tests at different times of day to see what your baseline performance actually is, and document the results so you can see when things start degrading.
Periodically push your network by simulating heavy load. This reveals capacity limits and bottlenecks that only show up when you're at peak usage.
Test how your actual critical applications perform on your network. Theoretical metrics matter, but what matters more is that your team's tools actually work when they need them.
Network reliability engineering is the practice of designing, building, and maintaining networks where reliability comes first. Network reliability engineers focus on building redundant systems, setting up proactive monitoring, creating rapid incident response, and improving based on what the data tells them.
This engineering approach treats reliability not as an afterthought but as a foundational requirement that influences every design decision.
What are some network reliability tools available to businesses? Several categories work together to provide comprehensive reliability management:
The key is getting visibility across your entire network so you can find and fix problems before they become outages.
Once you've measured your current performance, there are several proven strategies to actually improve reliability.
In any network, single points of failure are the enemy of reliability. Build in backup systems through multiple internet connections from different providers, redundant hardware, and automatic failover. 86% of organizations have adopted multi-cloud strategies for exactly this reason3 – distributing risk across multiple platforms means an outage at one provider doesn't take you down.
Your underlying network connection determines the ceiling of possible reliability. Fiber-based connections like the ones we provide at Fatbeam are inherently more reliable than copper alternatives because they're not vulnerable to electromagnetic interference or weather degradation.
Most reliability issues are preventable. Make sure to update firmware when patches are available, replace aging equipment before it fails, and keep thorough documentation of your network architecture.
Wireless network reliability requires specific attention. Use modern Wi-Fi 6 equipment, position access points carefully, and consider mesh networking for larger spaces.
Your internet service provider directly impacts your network reliability. Look for providers with strong SLAs, dedicated connections instead of shared ones, and proven track records of uptime.
Real network reliability requires the right combination of infrastructure, monitoring, and provider partnerships. While internal tools and practices matter, your underlying connectivity is where it all starts – that's the foundation everything else builds on.
