NTT will split purchased subsidiary Verio into three and pull it into existing business units, the company has said.

Verio's US operations will become part of NTT America, its European operations part of NTT Europe, and NTT Singapore will take over the company's operations in South-east Asia. A global business division will also be established to oversee the needs of global clients, the company said.

"It will help us streamline our ability to provide services to customers," said a spokesman. Users can expect to see more convenience from the reorganisation because the regional NTT units will be able to provide more of a one-stop shopping service for networking and hosting services, the company claimed.

NTT cited the US market as one area where such one-stop service was becoming increasingly important, particularly as the regional operators begin to encroach on its business space.

NTT bought Verio in September 2000 for $5.5 billion in a deal that sparked a US government review of the deal on national security concerns. The FBI was concerned that its ability to tap Verio's Internet lines would be hindered by the deal.
