The crash of the data server caused racers to be unable to use DRS in the last race of this season 17.
Drivers can only switch on the DRS at certain points of the line if they are less than a second behind the car. F1 racing director Michael Masi said the FIA did not allow racers to use the moving rear wing system because they were not able to provide them with adequate information.
“The data server has crashed. The time was still working, as we all saw. But this system crashed and we immediately disabled it. The system could not be reactivated until we were 100% certain that everything was working optimally. Unfortunately, racers were not able to use DRS during this time, but this measure was absolutely necessary if we were to ensure a regular race. “
