EXHIBIT 23.3


                 NOTICE REGARDING CONSENT OF ARTHUR ANDERSEN LLP

         On June 19, 2002, Iron Mountain Incorporated (the "Company") dismissed
Arthur Andersen LLP ("Arthur Andersen") as its independent public accountants
and engaged Deloitte & Touche LLP as its new independent public accountants for
the fiscal year ending December 31, 2002. For additional information, see "Item
9. Changes in and Disagreements with Accountants on Accounting and Financial
Disclosure" in this Annual Report on Form 10-K for the year ended December 31,
2002 (the "2002 Form 10-K").

         The 2002 Form 10-K is incorporated by reference in the Company's
previously filed registration statements on Forms S-3 (File No. 333-75068), S-4
(File No. 333-91577) and S-8 (File Nos. 333-43787, 333-89008 and 333-95901)
(collectively, the "Registration Statements"). The Company was unable to obtain
the consent of Arthur Andersen to the incorporation by reference into the
Registration Statements of the audit report of Arthur Andersen with respect to
the Company's consolidated financial statements for the fiscal years ended
December 31, 2001 and 2000. Pursuant to Rule 437a under the Securities Act of
1933, as amended, the Company elected to omit the consent of Arthur Andersen
from the Registration Statements. Because Arthur Andersen has not consented to
the incorporation by reference of their report in the Registration Statements,
purchasers of securities offered pursuant to the Registration Statements on or
after the filing of the 2002 Form 10-K will not be able to recover against
Arthur Andersen under Section 11 of the Securities Act for any untrue statements
of a material fact contained in the consolidated financial statements audited by
Arthur Andersen and incorporated by reference in those consolidated financial
statements, or, any omissions to state a material fact required to be stated in
those consolidated financial statements.
