As a subsidiary of WorldCom, UUnet remained one of the largest ISPs in the world. Its global pipe-line — more commonly referred to as an Internet "backbone" — carries more than 2,500 points of presence (areas with local phone line access) in North and South America, Europe, Asia, and Australia.
UUNET was purchased by MFS, later taken over by WorldCom, which eventually bought MCI. He later became WorldCom's Chief Operations Officer. Sidgmore worked to revive WorldCom after disgraced CEO Bernard Ebbers left.
UUNET held very strong engineering principles and commitment to not only produce network designs that would scale and provide highly availability but to test such design as well as the hardware and software in the engineering lab. Nothing went into the network that wasn't qualified and validated by a specific series of tests internally.
The company was formed as the first commercial ISP in the UK by Unipalm in 1990 as The Public I.P. Exchange Ltd (PIPEX), founded by Peter Dawe.  In mid 1992, it began operating a 64k transatlantic leased line to UUNET and another to JANET.   One of its first customers was Demon Internet, shortly followed by the BBC.
