Don’t they use halon as well? I’m not into conspiracy theories in general but i can’t believe that a halon system also failed without proof.
Halon is old tech. I believe the EPA scuttled halon as an allowed suppression chemical in the late 90s, but I could be off by a decade.
FE13 and newer FE25 are the standards for data centers, as they’re non-conductive and server/switching equipment will be unharmed when it’s deployed.
And obviously with sprinklers still being used as a last resort, unless this data center was not equipped with redundant or failover fire suppression (which I highly doubt), a failure of multiple systems is so unlikely as to be improbable and difficult to comprehend.
