Total eclipse of the Internet: traffic impacts in Iceland, Spain, and Portugal

KUALA LUMPUR, 14 AUGUST 2026 —

Total Solar Eclipse Casts Shadow Over Internet Traffic in Europe, Data Shows

The eclipse, the first to cross mainland Europe in two decades, began its path over the North Atlantic before moving over Iceland and northern Spain and Portugal near local sunset. While most of Western Europe experienced a deep partial eclipse, countries like Sweden, Denmark, and Poland saw only minimal obscuration of the sun.

Cloudflare’s analysis of HTTP request volumes in five-minute intervals revealed a clear correlation between the eclipse’s path and internet activity. Traffic in countries along the path of totality—including Iceland, Ireland, the United Kingdom, France, Spain, and Portugal—dropped significantly as the moon obscured the sun, rebounding once the eclipse passed. The most dramatic declines were observed in Iceland, Spain, and Portugal, where traffic fell by roughly 15% to 30% compared to a normal Wednesday evening baseline.

The data, which compared eclipse-day traffic against the median of the previous three Wednesdays, showed that regions with deeper eclipse coverage experienced sharper declines. For instance, Norway and Sweden saw slight increases in traffic, while Denmark recorded minimal changes. The timing of the traffic drops aligned precisely with the eclipse’s peak obscuration in each location, reinforcing the link between the natural phenomenon and online behavior.

In Spain and Portugal, where the eclipse was total, internet traffic plunged by up to 46.7% at its lowest point. The decline began in Iceland around 15:35 UTC, with traffic troughs mirroring the eclipse’s progression across Europe. By contrast, countries with shallow partial eclipses, such as Poland and Denmark, saw little to no impact on internet activity.

The findings underscore how major physical events can temporarily reshape digital behavior. Cloudflare’s report suggests that the eclipse’s influence extended beyond mere distraction—it created a measurable shift in online engagement, with people stepping away from screens to witness the rare event. Once the eclipse subsided, internet traffic quickly returned to normal levels, leaving behind a snapshot of how collective human attention can momentarily realign digital activity.

For Malaysia, where internet penetration is high and digital engagement is a key part of daily life, the eclipse’s impact offers a case study in how large-scale events can influence online behavior. While Malaysia was not in the eclipse’s path, the data highlights the broader trend of digital activity being shaped by external factors, from sporting events to natural phenomena.

Industry analysts note that such patterns are valuable for understanding internet usage trends, particularly in regions with high digital adoption. The eclipse’s effect on traffic also serves as a reminder of the internet’s role as a reflection of human behavior, where real-world events can momentarily disrupt the digital landscape.

Cloudflare’s Radar platform, which tracks internet traffic patterns globally, provides further insights into how major events shape online activity. The company’s data visualization tools allow users to explore these trends in real time, offering a deeper understanding of the interplay between physical and digital worlds.
