Businesses invoked their emergency backup plans in the aftermath of the bomb attacks in London.
The London Clearing House, LCH.Clearnet, was evacuated and operations resumed at an alternative site, after the series of explosions on the London transport network. LCH clears stock markets, commodities and energy trades.
Lorraine Darke, a spokeswoman for the Business Continuity Institute (BCI), said that she believed one retail member, Sainsbury’s, had successfully invoked its emergency backup plan.
She added that the institute’s members “are out there working flat out, and have not reported back. The only problems people have experienced have been with pagers and mobiles”.
Meanwhile, Vodafone, the UK's largest network operator, was forced to adopt “access overload” measures as its mobile network struggled with the increase in calls. A statement said the excessive number of calls had caused outages as the operator set aside capacity for phone calls to the emergency services.
“Following the major incident in London today, Vodafone London switches are at capacity (which is very rare) so we're having to go into 'access overload' procedures, which means freeing up a proportion of capacity across London to ensure the police and emergency services can communicate," the company said.
Orange, T-Mobile and O2 are also reported to have said their networks were experiencing congestion today.
