European Internet Traffic Fell Up to 46.7% During 2026 Total Solar Eclipse

Summary

  • Cloudflare Radar found HTTP traffic across eclipse-affected Europe dropped in near lockstep with maximum solar obscuration on Aug. 12, with the deepest declines in countries along the path of totality.
  • 15% to 30% traffic dips were typical in regions that saw totality or deep partial coverage, while areas with shallow eclipses showed little change and some Nordic markets even posted slight increases.
  • Iceland, Spain and Portugal recorded the biggest falls, while Denmark saw the smallest overall change and Poland quickly returned to normal levels after maximum eclipse.
  • 5-minute traffic data compared with the median of the previous three Wednesdays showed activity rebounding within minutes, indicating the slowdown reflected people watching the eclipse rather than network disruption.
  • The eclipse was the first total solar eclipse to cross mainland Europe in 20 years, offering a continent-wide example of how a shared physical event can briefly redirect digital behavior.
