As audiences around the world stream the 2026 FIFA World Cup, the conversation will not only focus on the matches on the pitch, but on the production quality and scale of the delivery infrastructure behind them. According to a Harris Poll survey, more than half of Americans plan to stream at least one match. This massive, simultaneous global demand does more than reveal viewing habits. It actively tests the limits of delivery systems.
Even as encoding and streaming technologies improve, viewers encounter buffering delays and sudden drops in quality when demand spikes. While these issues are often blamed on the streaming platforms themselves, they actually point to a deeper structural constraint within the underlying network architecture.
Streaming this year’s tournament reveals a problem that has been quietly building for years as video has become the dominant workload on the internet. It’s a clear signal that the internet is approaching another major inflection point, one that will require completely rethinking how content is delivered at scale.
Every Network Evolution Starts With a New Application
Network evolution is not new. In the 1990s, telecom networks were built for voice traffic and predictable calling patterns. When consumers shifted in droves to the early internet, those assumptions broke down. Calls that typically lasted minutes turned into online sessions that lasted hours.
This resulted in regulatory filings to the FCC arguing that because dial-up users were holding switches open indefinitely, a non-internet user in the same neighborhood trying to dial 911 could receive a busy signal. The existing network was simply not optimized for how it was suddenly being used.
The industry’s answer back then was not to add more capacity, but build an entirely new architecture designed for data. The industry transitioned from a voice network that also carried data to a data network that also carried voice, enabling the modern internet economy we rely on today. Much of that lesson remains the same – as applications change, networks must change with them.
However, we’re seeing the cycle of reinvention being driven by a different kind of application categorized as real-time, high-bandwidth video at global scale. Unlike previous transitions, this shift is continuous and is starting to expose real strain on the network closest to the end user.
Pressure Is Building at the Edge
Historically, the default response to rising video demand has been to add more fiber. But the user experience still degrades during peak moments. Streams begin at a lower resolution to decrease startup time, and bitrates are automatically reduced when networks get congested.
During major streaming events, viewers regularly lose clarity or stability at the exact moments they care most about. These are not isolated glitches, they are symptoms of systemic, structural strain.
This constraint is most visible at the network edge—specifically in last-mile infrastructure connecting content to homes and devices. Every duplicated stream consumes capacity in a segment of the network that is already heavily loaded. At scale, continuing to rely on this level of delivery inefficiency becomes hard to justify.
The Internet Has Quietly Become a Video-Heavy Data Network
The internet today is now a data network carrying video—but more accurately, it has become a network dominated by massive, simultaneous "hot" data workloads. While streaming platforms and live sports have radically reshaped traffic patterns to the point where video now represents roughly 80% of internet traffic, this structural strain isn't exclusive to video.
We see the exact same architectural bottleneck when millions of devices simultaneously pull a critical mobile update, when gaming platforms drop a massive software patch, or when autonomous vehicle fleets sync hyper-localized HD maps.
However, nowhere is this delivery challenge more acute, or visible, than during a massive live sporting event. The core issue stems from an architectural reliance on a one-to-one delivery model (unicast) for content that is inherently one-to-many (multicast).
Under the traditional unicast model, every viewer receives an individual stream from the content delivery network, even when millions of people are watching the exact same frame at the exact same millisecond. Conversely, multicast is a one-to-many model, where a single transmission can be distributed efficiently to all recipients at once. Live sports are naturally shared experiences. Forcing networks to duplicate and deliver the same stream millions of times over severely strains the access networks closest to the consumer.
The Next Evolution of Internet Infrastructure
Stepping into the next phase of internet infrastructure requires recognizing that not all traffic should be treated equally. We must acknowledge that video is now the dominant workload on the network, and that live, high-demand content requires a specialized approach.
As video continues to dominate global traffic, pressure on today’s legacy delivery model will only intensify. The opportunity ahead lies in aligning network architecture with actual consumption habits to eliminate unnecessary duplication where demand is highest.
This means shifting away from repetitive one-to-one delivery toward more efficient distribution models where a single transmission can be broadcasted across the edge, rather than recreated millions of times over. Streaming the World Cup isn’t breaking the internet. It’s revealing that the internet has already evolved into a data network carrying video, and its physical architecture must now evolve to match.
