👻MythBusters | “The Internet Has No Guarantees, It’s Only Best Effort”🎃

If you’ve ever had an Internet outage, chances are you’ve heard this excuse from your ISP, FNO, or WISP:

“The Internet is a best-effort service with no guarantees.”

This explanation conveniently shifts the blame onto the nebulous concept of "the Internet" and away from what often turns out to be the real culprit—last-mile telecommunications. But is it true that the Internet has no guarantees? Or is this just a myth used to mask poor service? Let’s bust it wide open, MythBusters-style.

The Origins of the Internet | Resilience Built In

To understand this myth, we need to go back to the birth of the Internet. Born from ARPANET in the late 1960s, the Internet was designed by researchers and military strategists with one primary goal: resilience.

• The core idea was to create a network that could withstand failures, whether due to physical disruptions or technical issues. This is why the Internet uses packet switching and diverse routing protocols like BGP (Border Gateway Protocol).

• It was specifically engineered with parallel paths to ensure redundancy. If one route failed, traffic would automatically reroute through alternative paths.

The Internet wasn’t designed to fail—it was designed to bypass failures.

The Last Mile | The True Source of Most Problems

Now, let’s zoom in on where the problems actually occur: the last mile. This is the connection between a user’s premises and their service provider’s core network. Here’s why the last mile is NOT the Internet:

1. Last Mile is Fully Managed
   Unlike the open and distributed nature of the Internet, the last mile is a tightly controlled service. ISPs, FNOs, and WISPs own and operate the infrastructure, including fiber, wireless towers, and routing equipment.

2. Service Levels Are Agreed Upon
   Last-mile providers often sign SLAs (Service Level Agreements) with customers, guaranteeing uptime, latency, and repair timelines. Yet, when issues arise, the "best effort" excuse gets thrown around, even though the service is anything but unmanaged.

3. Data Centres and Breakouts Are Highly Reliable
   Most ISPs break out to the Internet through data centres with five-nines (99.999%) uptime. These facilities have redundant power, cooling, and connectivity. Similarly, cloud providers boast high availability across multiple zones and regions.

4. Robust National and International Infrastructure
   Countries often have multiple redundant long-distance circuits and submarine cables. These are managed and monitored to ensure stability and resilience. If one fails, traffic shifts to an alternate route.

Debunking the Myth | The Internet Has No Guarantees

Let’s examine why this myth is false:

1. The Internet's Design Philosophy Ensures Redundancy

The global Internet is built on decentralized protocols like BGP. Failures in one path don’t affect the overall network because traffic is rerouted dynamically. This design philosophy has made the Internet incredibly resilient, with outages generally limited to specific regions or services.

2. Local Failures Are Often the Problem

Most Internet outages aren’t caused by the Internet itself but by localized issues in the last mile:

• Fiber cuts

• Power failures at wireless towers

• Equipment malfunctions at customer premises

These problems are entirely within the control of the ISP, FNO, or WISP.

3. Data Centres and Cloud Providers Have Predictable Uptime

The backbone of the Internet—data centres and cloud infrastructure—operates at extremely high availability. For example:

• AWS, Google Cloud, and Azure regularly achieve 99.99% or higher uptime.

• Tier 3 and Tier 4 data centres, where many ISPs colocate their equipment, also offer near-perfect reliability.

4. Repair Timelines Are Predictable

ISPs and last-mile providers often know exactly how long repairs will take, whether it’s a few hours for a cable splice or a day for equipment replacement. Claiming the unpredictability of the "Internet" as the cause of delays is a cop-out.

The Reality | It’s Not the Internet, It’s the Last Mile

The excuse that "the Internet is only best effort" is simply a deflection. When examined critically, the Internet itself—its backbone, protocols, and infrastructure—is a marvel of engineering designed for reliability and resilience.

The real issue lies in the last mile, where:

• Redundancy is often absent.

• SLAs aren’t honoured.

• ISPs fail to invest in robust failover mechanisms, such as SD-WAN or secondary circuits.

How to Bust the Myth for Good

Businesses and consumers can take steps to protect themselves from last-mile failures and ensure uninterrupted connectivity:

1. Adopt SD-WAN
   SD-WAN solutions, like Fusion’s, offer:

   • Dynamic failover between multiple last-mile links.

   • Packet-level redundancy to prevent session drops during outages.

2. Diversify Connectivity
   Use multiple ISPs or redundant technologies (e.g., fiber and LTE) to eliminate single points of failure in the last mile.

3. Demand Transparency
   Hold providers accountable for their SLAs and demand transparent reporting on outages and repair times.

Wrapping up on Why the Myth is Busted

The Internet isn’t the problem—it’s the solution. Its design is inherently resilient and reliable, with robust failover mechanisms built into its DNA. The real culprit behind outages is often the last mile, where ISPs and FNOs fail to deliver on their promises.

It’s time to stop blaming the Internet and start addressing the real issues in last-mile telecommunications. By adopting modern solutions like SD-WAN and demanding better accountability from providers, businesses and consumers alike can enjoy the true benefits of the Internet without falling victim to outdated myths.
