Unless they get the money required to keep the network running for the next two weeks, they will withdraw their support at 3 a.m. on Wednesday, they said Tuesday. The network carries up to a third of Europe's IP traffic.
This will effectively shut the network down, although the liquidators only say "it is likely that this will lead to disruptions of the network in the immediate future, and eventually to a complete close down of the network."
"I'm not sure how much credibility yet another ultimatum has," said Graham Kinsey, staff spokesperson for KPNQwest's Ebone operations center. "This is going to be viewed as idle threats."
Workers at Ebone on Monday said that they areto keep the network running, independently, if no buyer is found by the end of June.
KPNQwest has averted other shutdown threats recently. Friday, the bankrupt company's laid off, which had been working without pay, said they would turn off the network if they were not paid. Workers called off the action after liquidators for the company agreed to pay some of them through the end of the month.
Earlier last week, the company's liquidators said they'd close the operations if customers did not pay up-front. That deadline was extended to the end of June.
