       Iron Mountain Engages Deloitte & Touche LLP as Independent Auditors



Boston, MA - June 19, 2002 - Iron Mountain  Incorporated (NYSE: IRM), the global
leader in records and information  management services,  today announced that it
has engaged  Deloitte & Touche LLP as its  independent  auditors  for the fiscal
year ending  December 31, 2002  replacing  Arthur  Andersen LLP in that capacity
effective  immediately.  The  decision  to dismiss  Arthur  Andersen  and engage
Deloitte  &  Touche  was made  after  careful  consideration  by the  Audit  and
Executive  Committees  of the  Iron  Mountain  Board  of  Directors  and  senior
management.  The  decision was not the result of any  disagreement  between Iron
Mountain  and  Arthur  Andersen  on  any  matter  of  accounting  principles  or
practices, financial statement disclosure, or auditing scope or procedure.

"It is with sadness that we end our relationship with Arthur Andersen. They have
been  great  partners   throughout  our  time  as  a  public   company,   always
professional,  always  providing  the highest  level of  service,"  said Richard
Reese,  Iron  Mountain's  Chairman and CEO.  "Unfortunately,  Arthur  Andersen's
current  difficulties  and uncertain future convinced the Board that this change
was in the best  interest of our  shareholders,"  he added.  "We look forward to
working with Deloitte & Touche in their new role as our  independent  auditors,"
said Reese.
