In 1997, the company changed its name to Metromedia Fiber Network, Inc. (“MFN”), and was a member of the NASDAQ-100 index. In 1999, MFN acquired AboveNet Communications, Inc., a data center facility and Internet connectivity provider, as well as its subsidiary PAIX.net, Inc. (PAIX), an operator of Internet peering exchanges. In 2000, MFN acquired M.I.B.H., Inc., a networking consultancy operated by Paul Vixie, for $51 million in cash and stock. In 2001, MFN acquired SiteSmith, Inc., a provider of managed web-hosting services. The combined entity provided a range of services for the Internet market, including metropolitan area networks, data centers and IP network services, with former M.I.B.H. employees taking key engineering and operational positions. As a result of the collapse of the dot-com bubble, MFN — like many other similar companies — entered a severe liquidity crisis. The company filed for Chapter 11 bankruptcy in May 2002. As part of the Chapter 11 process the company sold off non-core assets, including its data centers, in the U.S. and mainland Europe, retaining a smaller but more viable footprint. The reorganized company changed its name to AboveNet when emerging from bankruptcy in September 2003, and traded on the New York Stock Exchange as ABVT. June 6, 2012 AboveNet was acquired by Zayo Group for $2.2B, 13% Premium.〔(【引用サイトリンク】title=AboveNet Acquired by Zayo Group For $2.2B, 13% Premium )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AboveNet」の詳細全文を読む スポンサード リンク
