The European Space Agency has installed software to enable its web portal to handle the traffic peaks on its site when it reports on major events.
It is using Akamai's Edgesuite software, which temporarily caches web pages on thousands of servers around the world. This enables the site to deliver an effective 300Mbytes a second of data, although the agency's own bandwidth delivers only 1.5Mbytes a second.
The site encountered problems two years ago when the Mars Express space module went into orbit around the red planet. The increase in traffic meant some visitors were unable to access it at peak times.
