This statement on Schedule 13D (this Statement) relates to the Schedule 13D filed with the Securities and Exchange Commission on November 18, 2004, with respect to the Class A and Class B common stock, par value $0.01 per share, of Infonet Services Corporation, a Delaware corporation (Infonet), filed on behalf of the Reporting Persons, as defined below.

Item 2 is hereby amended in its entirety as follows:

ITEM 2. IDENTITY AND BACKGROUND

(a) - (c), (f) The names of the companies filing this Statement are BT Group plc, a public limited company organized under the laws of England and Wales (BT Group), British Telecommunications plc, a public limited company organized under the laws of England and Wales (British Telecommunications) and BT United States L.L.C., a limited liability company organized under the laws of Delaware (BT US LLC, and, together with BT Group and British Telecommunications, the Reporting Persons). The principal business address of BT Group and British Telecommunications is BT Centre, 81 Newgate Street, London, EC1A 7AJ, England. The principal business address of BT US LLC is 11440 Commerce Park Dr., Reston, VA, 20190, USA. BT Group is the holding company for an integrated group of communications businesses and is listed on the London Stock Exchange and the New York Stock Exchange. British Telecommunications is a wholly owned subsidiary of BT Group and encompasses virtually all businesses and assets of the BT Group. BT US LLC is an indirect wholly owned subsidiary of, and is controlled by, BT Group, and provides communication related services and products in the United States through its subsidiaries. The name, citizenship, business address and present principal occupation of each executive officer and director of the Reporting Persons is listed on Schedule A attached hereto.

(d) Neither the Reporting Persons nor, to the Reporting Persons’ knowledge, any person named on Schedule A attached hereto is required to disclose legal proceedings pursuant to Item 2(d).

(e) Neither the Reporting Persons nor, to the Reporting Persons’ knowledge, any person named on Schedule A attached hereto is required to disclose legal proceedings pursuant to Item 2(e).

Item 3 is hereby amended in its entirety as follows:

ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

The total amount of funds required to pay the merger consideration pursuant to the Merger is approximately $965 million. These funds were obtained from BT Group.

Item 4 is hereby amended by adding the following:

ITEM 4. PURPOSE OF TRANSACTION

(a) - (b) On February 25, 2005, pursuant to an Agreement and Plan of Merger dated as of November 8, 2004 (the Merger Agreement), by and among British Telecommunications, Blue Acquisition Corp., a Delaware corporation and wholly owned subsidiary of British Telecommunications (Merger Sub), and Infonet, Merger Sub merged with and into Infonet, and Infonet became an indirect wholly owned subsidiary of BT Group (such events constituting the Merger).

The Merger Agreement was adopted by the holders of the majority of outstanding shares of the Class A and Class B common stock of Infonet at a special meeting of stockholders held on February 23, 2005. Pursuant to Stockholder Agreements dated as of November 8, 2004, as amended, certain stockholders of Infonet (see Schedule B attached hereto) (the Stockholders) voted the 161,403,358 shares of Infonet Class A common stock and 240,929,744 shares of Infonet Class B common stock severally beneficially owned by the Stockholders, constituting approximately 96.5% of the voting power of the outstanding Infonet common stock, to approve and adopt the Merger Agreement.

As a result of the Merger, each issued and outstanding share of Class A common stock, par value $0.01 per share, of Infonet not owned by British Telecommunications, Merger Sub or Infonet, other than the Appraisal Shares (as defined in the Merger Agreement), was converted into the right to receive $2.06 in cash, without interest, and each issued and outstanding share of Class B common stock, par value $0.01 per share, of Infonet not owned by British Telecommunications, Merger Sub or Infonet, other than the Appraisal Shares, was converted into the right to receive $2.06 in cash, without interest (the Merger Consideration). All such shares of Infonet common stock are no longer outstanding and were automatically canceled and retired and have ceased to exist, and each certificate previously representing any such shares now represents the right to receive the Merger Consideration payable in respect of such shares of Infonet common stock.

(d) David Lawrence Lee, Andrew McCauley, Chuck Pol and Kirsten Verderame, the directors of Merger Sub immediately prior to the effective time of the Merger, are the directors of Infonet until the next annual stockholder meeting of Infonet (or their earlier resignation or removal) and until their respective successors are duly elected and qualified, as the case may be. The officers of Infonet immediately prior to the effective time of the Merger are the officers of Infonet until the earlier of their resignation or removal or until their respective successors are duly appointed and qualified, as the case may be.

(e) Other than as a result of the Merger described in Item 4(a) above, not applicable.

(f) Not applicable.

(g) As of the effective time of the Merger, the certificate of incorporation of Infonet was amended to be in the form of the restated certificate of incorporation attached as Annex A to the certificate of merger filed by Infonet with the office of the Secretary of State of the State of Delaware on February 25, 2005 (the Certificate of Merger). The by-laws of Merger Sub, as in effect immediately prior to the effective time of the Merger, are the bylaws of Infonet (the Bylaws) until thereafter changed or amended as provided therein or by applicable law. Copies of the Certificate of Merger and the Bylaws are attached as Exhibits 3 and 4 to this Statement.

(h)-(i) The Infonet Class B common stock will be deregistered under the Securities Exchange Act of 1934, as amended (the Exchange Act), and delisted from the New York Stock Exchange. Trading of Infonet Class B common stock was suspended prior to the opening of the market on February 25, 2005. On March 1, 2005, Infonet filed with the Securities and Exchange Commission a Certification and Notice of Termination of Registration under Section 12(g) and 15(d) of the Exchange Act on Form 15.

(j) Not applicable.

References to, and descriptions of, the Merger, the Merger Agreement, the Stockholder Agreements, the Certificate of Merger and the Bylaws as set forth herein are qualified in their entirety by reference to the copy of the Merger Agreement, the forms of Stockholder Agreement, the Certificate of Merger and the Bylaws, respectively, included as Exhibits 1, 2, 3 and 4, respectively, to this Statement, and such agreements are incorporated herein in their entirety where such references and descriptions appear.

Item 5 is hereby amended in its entirety as follows:

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER

(a) – (b) The Reporting Persons are beneficial owners of 100 shares of Infonet common stock or 100% of the outstanding shares of Infonet common stock following consummation of the Merger. These shares are owned directly by BT US LLC, which is a wholly owned subsidiary of British Telecommunications, which is in turn a wholly owned subsidiary of BT Group. British Telecommunications and BT Group are indirect beneficial owners of these shares. The Reporting Persons have shared power to vote or to direct the vote, and shared power to dispose or to direct the disposition of these shares.

(c) Except as described above, the Reporting Persons, and to the best of their knowledge the persons listed on Schedule A hereto, have not effected any transactions in shares of common stock of Infonet in the 60-day period preceding the date of this Statement.
