CHANGES IN REGISTRANT’S CERTIFYING ACCOUNTANT

Sify Limited (the “Company”) had changed its US GAAP auditors from KPMG (Registered), an Indian partnership (“KPMG India”), to KPMG LLP, a UK limited liability partnership (“KPMG LLP”), for the fiscal year ended March 31, 2004 at the request of KPMG India. As contemplated and disclosed in the Form 6-K filed on June 24, 2004, the appointment of KPMG LLP as the Company’s US GAAP auditors was expected to be transitory with the re-appointment of KPMG India as the Company’s US GAAP auditors anticipated upon completion of KPMG India’s registration with the U.S. Public Company Accounting Oversight Board (the “PCAOB”).

KPMG India has notified the Company of its registration with the PCAOB. The appointment of KPMG India as US GAAP auditors for the fiscal year ended March 31, 2005 has been approved by the Audit Committee of the Company.

The Company reports financial results in accordance with both US GAAP and Indian GAAP. Under the rules promulgated by the U.S. Securities and Exchange Commission (the “SEC”), the change from KPMG LLP to KPMG India for the fiscal year ended March 31, 2005 constitutes a change in the registrant’s certifying accountants. There has been no change in the Company’s Indian GAAP auditors, BSR & Co.

The reports of KPMG LLP on the Company’s financial statements for each of the fiscal years ended March 31, 2003 and 2004 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended March 31, 2003 and 2004 and through the date of change of auditors, there were no disagreements with KPMG LLP on any matter of accounting principle or practice, financial statement disclosure or auditing scope or procedure which, if not resolved to the satisfaction of KPMG LLP, would have caused them to make reference to the subject matter in connection with their reports on the Company’s financial statements for such years. There were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided KPMG LLP and KPMG India with a copy of the foregoing disclosures. Attached as Exhibit 99.1 is a copy of the letter of KPMG LLP, dated April 21, 2005, stating its agreement with such statements.
