Half the world’s Internet load is now being shouldered by a bankrupt WorldCom, but analysts and company officials say the worldwide network is safe – for now.

“The worst possible period where we were at most risk was the last few months, where there was great uncertainty,” WorldCom chief executive John Sidgmore told reporters Monday.

WorldCom is the owner of UUNet, a company that runs what’s known as a major Internet “backbone” – the computer infrastructure that is a mainstay of the Internet’s rivers of data.
