They aren't super common, but halon and other gas systems are just the right tool for the job. It can get inside the server chassis and doesn't damage equipment like a chemical application would. We won't know what went wrong at OVH until a proper post mortem comes out. These systems work by suppressing the flame reaction, but if the actual source was not addressed, it could reignite after awhile.
