Cern's website saw a 1,066% increase in traffic last week, as it started its Big Bang atom collision experiments.
Last week, the first beam in the Large Hadron Collider at Cern was successfully steered around the full 27 kilometres of the world's most powerful particle accelerator.
Expecting a surge in internet traffic on the day, Cern asked network provider Interoute to provide additional network capacity.
On 10 September, the day the experiments started, usage of the Cern website peaked from the usual 30Mbps to 350Mbps, an increase of 1066% per cent.
Gareth Williams, Interoute CEO, said: "This historic event was closely followed by people the world over. Cern not only had a boom in network connectivity to power the event itself, but also a spike in traffic at the Cern site in response to global demand for real-time updates."
Last week, a site associated with the main Cern website was hacked.
