Most modern data centres wouldn't have had this issue, at least in in Australia they use Argonite suppression systems, these work by using a gas that is a mixture of argon and nitrogen that suppresses fire by depleting oxygen in the the data hall.

I'm seeing quite a lot of repeated sentiment throughout the comments that Halon is illegal and is no longer used.

Is the situation "Halon is legal in Australia" or "Halon isn't actually illegal per se if you don't use a lot of it"?

Halons are being phased out because, being CFCs, they deplete the ozone layer.

Other gases like argon or FM200 are not Halons.

Halon and Argonite are unrelated.

I don't think Aussie dc's are all the same. Globalswitch in Sydney uses inergen but Equinix is using water at least at SY1 but I'm reasonably sure that GS is much older
