In May, HP built two data centers and blew one up to demonstrate disaster tolerance. VMS recovered first, in less than 14 seconds. The associated document said that it could have been adjusted to be less than 5 seconds.

At a high-tech ballistics center managed by National Technical Systems
in Camden, Arkansas, HP simulated a gas leak using real explosives that
resulted in a very real explosion and datacenter destruction.
What was blown up? Products from the entire spectrum of HP products,
including HP servers, HP StorageWorks products, HP Software and HP
Procurve networking products running in five operating
environments-HP-UX, HP OpenVMS, HP NonStop, Red Hat Enterprise Linux and Microsoft(r) Windows Server 2003.
