The IT infrastructure that will be supporting the Olympics and Paralympics Games this summer will be given its second and final round of testing this week.
The equipment, which includes 10,000 devices, will be tested over the next five days at the 17 Games' venues. The equipment will then remain at the venues until the event.
"We'll be stressing the system to a high degree," said Patrick Adiba, the chief executive of Atos Iberia, Olympics and major events.
"We'll be simulating a disaster recovery scenario so we can ensure operations can be back up and running in a matter of hours in the case of a disaster, through moving to another environment."
The testing will ensure the system can cope with the torrent of real-time data that is expected during the Games, and that the numerous IT teams at the venues are in good shape to deal with any security incidents that occur.
According to Adiba, during the last Games in Beijing, there were 16m security breaches every day of the event.
Adiba added that these security breaches included extremely low-threat incidents like a member of the Games' staff typing in the wrong system password.
The Games' mission control IT centre is the Technology Operations Centre (TOC), based in a building in Canary Wharf.
Each of the Games' IT teams at the venues will be responsible for the IT equipment housed in their building, and the TOC will take on an overarching monitoring role.
"But if something goes wrong across a number of venues then we will step in and take control," said Adiba.
