How the 2026 World Cup Impacted Internet Traffic
The digital reflections of a global phenomenon were examined.
1A Global Phenomenon
For 96 years, the World Cup has united nations and communities through a shared love of sportsmanship. However, such collective experiences are becoming increasingly rare in today's era of microtrends and algorithmic bubbles, where simultaneous global engagement in the same event is uncommon.

3Establishing a Traffic Baseline
To understand traffic changes during a match, it was essential to establish what 'normal' traffic levels look like. This was done by using the median traffic values from the preceding four weeks, which smoothed out daily fluctuations and provided a stable reference point.
4The Impact of Match Timing
The local start times of matches significantly influenced internet traffic. Matches played between midnight and 8 a.m. local time caused substantial traffic spikes, as fans stayed up or woke early to watch, sometimes doubling the usual traffic levels.
5Daytime Matches
Matches played between 9 a.m. and mid-afternoon did not cause significant traffic changes, as people were already online during these hours. In the early evening, a smaller traffic increase was observed, particularly on weekdays, as matches kept people connected during a time when usage would normally decline.
6The Bosnia-Herzegovina Example
In Bosnia-Herzegovina, a match played at 2 a.m. local time saw traffic surge well above normal levels as fans stayed awake to watch. Conversely, an evening match caused traffic to dip below normal, as people focused on the game rather than their devices.
7Brazil vs. Japan Match
The match between Brazil and Japan was watched 12 hours apart due to the time difference. In Japan, the match aired in the middle of the night, causing traffic to rise above normal levels. In Brazil, the match fell during normal waking hours, leading to a drop in traffic as people focused on the game.
8Matches That Moved the Internet Most
The matches that had the most significant impact on internet traffic were analyzed. For each match, the two-hour window after kickoff was examined, and traffic deviations from the baseline were calculated for each country. The absolute values of these deviations were used to measure the impact.
9A Surprising Result
The match that moved the internet the most was not the final or semifinal but the quarterfinal between Argentina and Switzerland, where Argentina won 3-1. This match caused a significant traffic fluctuation worldwide.
10Regional Traffic Patterns
The impact of matches on regional traffic patterns was also studied. Matches played during nighttime hours caused significant traffic spikes, while daytime matches had a lesser impact. This indicates that people altered their daily routines to watch the matches.
11Weekend vs. Weekday Differences
Traffic patterns differed between weekends and weekdays. On weekends, the morning traffic spike was more pronounced, while the evening increase was milder. On weekdays, a smaller traffic increase was observed in the evening.
12Conclusion and Significance
The 2026 World Cup had a significant impact on global internet traffic. The local start times of matches caused substantial fluctuations in traffic. These findings provide valuable insights for understanding the impact of future large-scale events on internet infrastructure.
