THE CUSTOMER
In a former vault building, DARZ GmbH operates a data
centre with what is likely to be the highest level of building
security in Germany.
Founded in 2010, DARZ GmbH
is a full service provider that
offers colocation/housing, managed services and data centre
solutions in an extraordinary
environment at its data centre
in Darmstadt. This is located
in the former vault building of
the Hessian State Bank and has
what is likely to be the highest
level of building security of any
data centre in Germany.
