The outage forced the UK Debt Management Office to extend bidding for a bond auction by 90 minutes. Another debt sale in Portugal was delayed from the morning to afternoon.The glitch, which Bloomberg has called an "internal issue" was fixed before 1:00pm BST."Our systems are returning to normal operations and Terminal functionality has been restored following a service disruption earlier today," says a spokesperson.
