Behind Milano Cortina 2026 was an exabyte-scale data system

Behind Milano Cortina 2026 was an exabyte-scale data system

Milano Cortina 2026 was not just a Winter Olympics. It was a giant distributed data system wrapped around a sporting event. The honest answer, though, starts with a limit: among the public materials reviewed from organisers, broadcasters and technology partners, there is no single official published total for all data used across the Games. What exists instead is a patchwork of numbers for streaming minutes, app usage, cloud production, network capacity, connected devices and broadcast output.

That matters because many viral summaries mix unlike metrics as if they describe the same thing. A peak traffic figure is not the same as total consumption. App opens are not the same as video delivery. Social engagements are not the same as network throughput. And 16.7 billion streaming minutes in the United States is not a global Olympics total. The biggest mistake in this topic is treating every impressive number as if it measured the same layer of the system.

The public record shows scale rather than one master total

Start with the broadcast core. Olympic Broadcasting Services said Milano Cortina 2026 would deliver more than 6,500 hours of content, including more than 900 hours of live competition and ceremonies, using more than 810 camera systems. Alibaba Cloud described the Games as another step in the IOC and OBS shift toward cloud-based, AI-enabled broadcasting, including upgraded real-time replay systems. That tells you immediately that the data story begins long before a fan presses play on a stream.

Then comes the audience layer. Olympics.com reported 110 million users across the Olympics web and app platforms, 120 million app opens during the Games, and more than 10 billion engagements across Olympic social media handles. Another official Olympics.com metric said the dedicated Olympic experience inside Brookhaven on Roblox had already generated more than 1.3 billion visits. Milano Cortina 2026 was a broadcast event, a mobile event, a social event and a gaming-platform event at the same time.

Europe’s numbers underline how wide the footprint really was. Warner Bros. Discovery said its streaming platforms HBO Max and discovery+ posted a 103 percent increase in total hours viewed versus Beijing 2022, with three times as many streaming viewers. The EBU said BBC Sport alone generated a record 83 million streams and more than 44 million streamed hours, while Austria’s ORF recorded 290 million minutes streamed. Those are not niche side metrics. They are evidence that demand was huge across multiple national markets simultaneously.

U.S. streaming alone points to a vast data range

The clearest hard number for delivered viewing volume comes from NBCUniversal. After the Games, NBC said Milano Cortina 2026 generated 16.7 billion minutes of streaming across its digital platforms in the United States alone. That equals about 278.3 million viewing hours.

Once you translate those hours into delivered data, the scale becomes easier to grasp. Netflix’s own guidance puts HD streaming at 3 Mbps and full HD at 5 Mbps, while the FCC’s consumer guidance puts typical HD video streaming in the 5 to 8 Mbps range. Using those reference rates as rough proxies, NBCUniversal’s U.S. streaming total works out to about 0.376 exabytes at 3 Mbps, 0.626 exabytes at 5 Mbps, and 1.002 exabytes at 8 Mbps. That is roughly 376 to 1,002 petabytes of delivered video from the U.S. digital audience alone. This is an estimate, not an official IOC total, but it is a grounded estimate built from disclosed viewing minutes and widely used streaming bandwidth references.

That single calculation changes the frame of the question. If one national market can plausibly land somewhere between the high hundreds of petabytes and about one exabyte in delivered streaming traffic, then the idea that the full Games were merely a “big internet event” is too small. They were exabyte-class in consumer video distribution terms even before you count the rest of the world.

The network on the ground looked like critical infrastructure

Milano Cortina 2026 also had an unusually demanding physical footprint. HPE said the Games covered 25 venues across Northern Italy and had to support more than 1 million connected devices. That is the kind of environment where data use is not just entertainment traffic. It includes timing systems, results feeds, media workflows, security, venue operations, accreditation, communications and spectator connectivity.

TIM’s post-Games summary makes that even clearer. The company said it enhanced more than 8,000 kilometres of transport-network infrastructure, built redundant connections of up to 100 Gbps across key Games locations, deployed a dedicated 5G network at San Siro capable of carrying hundreds of terabytes of data, provided more than 10,000 SIM cards and 4G/5G routers for operations, and more than 3,600 SIM cards for Olympic and Paralympic athletes. FiberCop added that all venues were tied into the national backbone with redundant optical paths to preserve continuity. This was telecom architecture designed for failure resistance, not ordinary event Wi-Fi.

Why so many online figures get muddled

This is also where the topic becomes messy. One widely repeated number is 1,225 Gbit/s, but that kind of figure refers to a peak-traffic moment in a specific broadcast or platform context, not to total data consumed by the entire Olympics. The EBU’s reporting used that figure in national broadcaster performance coverage, which is useful, but it is not a whole-Games byte count. The same problem applies in reverse to app and social metrics. A total like 120 million app opens or 10 billion engagements signals extraordinary digital demand, but it does not tell you how many bytes were transferred end to end.

The 16.7 billion minutes figure is another example. It is real and important, but it belongs to NBCUniversal’s U.S. platforms, not to Europe, not to Asia, not to host-country telecom traffic, and not to OBS internal production flows. Once you see that, the right way to read Milano Cortina 2026 is as a stack of overlapping data systems rather than one neat master number.

The most credible answer is broader and more cautious

So how much data was used during the Olympics 2026? The most defensible public answer is that no official consolidated total has been published, but the disclosed evidence points to a digital footprint that was enormous even by Olympic standards. U.S. streaming alone likely represented roughly 0.38 to 1.0 exabytes of delivered video, depending on bitrate assumptions. Add Europe’s record streaming performance, national broadcaster digital usage, cloud-based production, venue networking, app traffic, social video, operational systems and telecom backhaul, and the overall Milano Cortina 2026 ecosystem was almost certainly far above that baseline.

That is why the sharpest conclusion is not a fake precise total. It is this: Milano Cortina 2026 was an exabyte-scale Olympics in public consumption terms, and very plausibly a multi-exabyte digital event once the whole global system is considered. That last step is an inference, not an official Games statistic, but it is the inference most consistent with the published record. The modern Olympics no longer live only in stadiums and mountain venues. They live in fibre routes, cloud workflows, mobile apps, replay engines, edge devices and millions of simultaneous screens. Milano Cortina 2026 made that impossible to miss.

Data explained

Numbers in exabytes are so large that they quickly lose meaning unless they are translated into familiar objects. A few decades ago, a standard floppy disk held just 1.44 MB. By that measure, 1 exabyte would equal roughly 694 billion floppy disks. If those disks were stacked on top of one another, assuming a thickness of about 3.3 mm per disk, the stack would rise to around 2.29 million kilometres — nearly six times the average distance from the Earth to the Moon.

Another useful comparison is film. If we take a 90-minute full HD movie compressed with HEVC/H.265 to around 1.5 GB, then 1 exabyte would equal about 667 million films. That is the kind of scale involved when a modern Olympic Games becomes a global digital delivery system rather than only a television event.

Data valueWhat it means
0.376 exabyteThis is the conservative estimate for U.S. Olympic streaming based on 16.7 billion viewing minutes delivered at around 3 Mbps. That equals 376 petabytes, or 376 million gigabytes. For scale, that is enough data to fill about 1.47 million smartphones with 256 GB storage.
0.626 exabyteThis is the mid-range estimate if the same viewing volume was delivered at approximately 5 Mbps, a more typical full-HD streaming level. That equals 626 petabytes, or 626 million gigabytes. In more tangible terms, it would fill around 2.45 million smartphones with 256 GB storage.
1.002 exabyteThis is the upper-end estimate if average delivery was closer to 8 Mbps, which reflects higher-quality video distribution. That equals 1,002 petabytes, or just over 1 billion gigabytes. For perspective, that is close to filling 3.9 million smartphones with 256 GB storage.
1 exabyteAs a benchmark, 1 exabyte equals 1,000 petabytes, 1 million terabytes, or 1 billion gigabytes. It is also roughly equal to 694 billion floppy disks with 1.44 MB capacity, or about 667 million 90-minute full HD films if one compressed HEVC/H.265 movie is estimated at 1.5 GB. If those floppy disks were stacked, the pile would stretch to roughly 2.29 million kilometres.

Note: These figures use decimal units, where 1 exabyte = 1,000 petabytes.

This is why exabyte-scale language matters in the context of the Olympics. It shows that the Games are no longer defined only by athletes, venues and television audiences. They are increasingly shaped by massive digital delivery systems that move video, metadata, replays, mobile content and cloud-based production across networks at extraordinary scale. Once the numbers are translated into floppy disks, millions of smartphones or hundreds of millions of films, the size of that infrastructure becomes far easier to understand.

How long would it take to download 1 exabyte at 100 Mbps?

One of the easiest ways to understand how enormous 1 exabyte really is is to stop thinking about storage and start thinking about time. At a download speed of 100 Mbps, which still sounds fast in everyday life, downloading 1 exabyte would take about 925,926 days — or roughly 2,537 years. That is the kind of number that instantly shows why exabyte-scale data belongs to telecom backbones, cloud platforms and global content networks, not to ordinary internet connections.

Here is the calculation step by step:

1 exabyte = 1,000,000,000 GB

To convert that into bits:

1 GB = 8,000 megabits

So:

1 exabyte = 1,000,000,000 × 8,000 megabits = 8,000,000,000,000 megabits

Now divide by the download speed:

8,000,000,000,000 Mb ÷ 100 Mb/s = 80,000,000,000 seconds

Then convert seconds into days:

80,000,000,000 ÷ 86,400 = 925,925.9 days

And finally into years:

925,925.9 ÷ 365 = 2,536.8 years

Result: downloading 1 exabyte at 100 Mbps would take about 2,537 years.

That comparison makes the Olympic data story much easier to grasp. A home connection can feel fast when you are downloading a film or streaming a match. At exabyte scale, though, that same speed becomes almost meaningless. It is the difference between carrying a glass of water and trying to drain a lake with it.

At 100 Mbps, downloading 1 exabyte would take about 2,537 years — not years in any ordinary sense, but millennia. That is the clearest possible measure of modern Olympic data: it no longer belongs to consumer internet, but to the world of backbone networks, cloud platforms and infrastructure built for global scale, said Jan Bielik, CEO and Founder.
