We decided to explore why so many organizations are still relying on outdated failover methods that were never built for today’s cloud-first, always-on world. So here’s what we found out…

To be clear, we didn’t invent failover. We just made it stop breaking everything.

Key Takeaways

  • Most enterprises rely on outdated or misapplied internet failover methods that disrupt active sessions and degrade business performance.
  • Common business continuity strategies include Border Gateway Protocol (BGP), traditional dual-WAN failover, and LTE with NAT—each with significant technical, operational, and financial drawbacks.
  • Big Network’s Static IP Anywhere (SIPA) offers cloud-based failover with static IP persistence, multi-carrier support, and seamless sub-second connectivity.
  • SIPA ensures true internet redundancy, business continuity, and optimized customer and employee experience across any internet provider or device.

This quote reframes everything:

Failover exists. It’s everywhere. But in its current form, it breaks more than it protects.

There’s a surprising truth in modern enterprise networking:
The bigger the company, the more fragile the internet failover.

At face value, that shouldn’t be the case. Large organizations have access to sophisticated IT tools, highly-skilled teams, and enterprise budgets. But when it comes to connectivity—the internet infrastructure that underpins everything from cloud apps and real-time payments to remote access and customer experiences—most are relying on solutions that weren’t built for how business is done today.

From the outside, it looks redundant. Resilient. Rock solid. But under the hood, it’s fragile. Failover happens. The IP changes. Sessions drop. And it costs money.And the costs are real: Thirty-one percent of businesses report that internet outages cost them over $1.2 million annually. That’s not just lost sales—it’s downtime, IT labor, customer frustration, and broken trust.

Why Legacy Methods Used to Work

Ten or fifteen years ago, traditional failover strategies were enough. Businesses were more centralized. Most applications lived on-premise. Cloud adoption was minimal, and mobile access wasn’t mission-critical. If a retail location or clinic lost connectivity for a few minutes, the impact was tolerable.

  • Most apps didn’t require real-time sync
  • Sensitive operations happened in-house, not online
  • Failover delays were measured in minutes, not revenue

The demand for uptime just wasn’t what it is today.

But now, everything runs through the cloud:

  • Retail chains process payments through cloud-based POS
  • Healthcare systems sync patient data and virtual care in real time
  • Distributed teams rely on SaaS tools and always-on VPNs

Today, a single dropped session isn’t a minor annoyance—it’s a failed transaction, a lost medical record update, or a broken customer interaction.

Back then, failover was a safety net. Today, it needs to be invisible. And that’s a completely different level of expectation.

And it’s not just operationally critical. It’s competitive. Eighty percent of customers say the experience a company provides is as important as its products or services. Failover that disrupts customer experience is no longer acceptable.

Legacy methods weren’t wrong. They’re just no longer enough.

Let’s explore the most common internet failover strategies still in use, why they often fail at scale, and how SIPA redefines the category of resilient connectivity for modern businesses.

1. Border Gateway Protocol (BGP): A Legacy Tool Misapplied

What It Is: BGP is a complex, decades-old protocol that large internet service providers use to route traffic across the internet. When enterprises adopt it, they’re trying to make multiple internet connections look like one seamless service to the outside world.

Why It’s Used: It allows an organization to use more than one ISP while keeping the same static IP address—which is important for keeping systems running during outages.

Why It Fails Most Businesses:

  • Requires highly specialized IT skills to configure and maintain
  • Needs dedicated circuits and an "ASN" (a registered internet ID)
  • Demands ownership of large blocks of public IP addresses, which are expensive and scarce

It’s like launching a rocket just to pick up groceries.

For a business with hundreds of locations—say, a retail chain with POS systems at each store—this setup is wildly impractical. Each site would need expensive hardware, static IPs, and dedicated technical support.

There’s always that one guy who set it up in 2016 and swore never to touch it again. That’s your single point of failure.

2. Traditional Dual-WAN Failover: The Illusion of Redundancy

What It Is: A "dual-WAN" router connects to two internet providers (for example, Comcast and Verizon). If one connection fails, the other kicks in.

Why It Sounds Good: It’s cheap, easy to set up, and gives IT teams confidence that they’ve got a backup in place.

Why It Fails in Practice:

  • When the failover happens, the business gets a new IP address
  • That change breaks live connections—Zoom calls drop, transactions fail, and cloud apps disconnect
  • Everything technically "works," but nothing stays online smoothly

The failover works. The session doesn't. And that's the disconnect.

It’s like being in the middle of a customer checkout and your terminal reboots. You didn’t lose internet—but you lost the sale.

If you're running point-of-sale systems, booking engines, or video calls across multiple locations, every IP change is a potential disruption.

3. LTE + NAT Failover: Clever, But Still Incomplete

We love LTE. I just don’t trust it to carry my identity. It gets you back online, but it doesn’t keep you connected.

What It Is: Some businesses add LTE or 5G internet (via SIM cards) as a wireless backup. These often run behind NAT, a method that shares one IP address across many devices.

Why It Sounds Smart: It provides a backup that’s immune to cable cuts and local outages. It’s wireless, so it can connect even when primary lines fail.

Why It Still Breaks Things:

  • These backups usually come with dynamic IPs that change frequently
  • Session-based services like VPNs or payment systems can't tolerate sudden IP changes
  • NAT makes it harder to monitor or troubleshoot problems when they occur

You’ve built a really expensive ‘sometimes it works’ system. That’s not resilience. That’s duct tape.

4. Static IP Anywhere (SIPA): The Better Way

What It Is: SIPA is a new model for internet failover. Instead of tying your IP address to your internet provider, it gives you a static IP address from the cloud that never changes—even when your internet connection does.

Why It Works:

  • SIPA creates an encrypted tunnel between your location and the cloud
  • This keeps your IP address consistent, no matter which ISP or connection you’re using
  • Failover happens in 250 milliseconds—not minutes

Failover goes from session killer to non-event. Your VPN stays up. Your customer doesn’t notice. And that’s the point.

SIPA is like giving every store or site its own digital passport. You can fly Delta, Southwest, or Spirit. Doesn’t matter. You still land in the same country.

This matters for any company with distributed teams, retail locations, kiosks, or sensitive applications that rely on consistent connectivity.

Why This Matters to Business Leaders

Connectivity is the foundation of modern business—whether you’re selling coffee, routing packages, or managing cloud-based systems.

Without seamless failover, you're exposed to:

  • Lost revenue during payment processing failures
  • Employee downtime as systems reconnect
  • Customer dissatisfaction from broken experiences

SIPA aligns with what executives care about:

  • Business continuity: No disruptions during provider outages
  • Customer experience: No delays, no transaction failures
  • IT efficiency: No expensive routers or BGP configs
  • Scalability: Roll out to 1,000 locations without 1,000 headaches

We didn’t invent failover. We just made it stop breaking everything.

Final Word

Most businesses don’t need more internet. They need a smarter internet.

Failover isn’t about having a second connection. It’s about keeping your business running without anyone noticing there was ever a problem.

SIPA is built for today’s internet-driven economy: cloud-based, always-on, and distributed across locations.

Let’s stop settling for failover that fails. Let’s make the internet unbreakable.
