999 call service 'back to normal' after power loss
Emergency calls to the Welsh Ambulance Service have returned to normal after its computer system lost power.
The service is still catching up with a backlog caused by the failure of its IT systems on Wednesday.
Health chiefs said they were continuing to work on resuming full normal service.
Some of their vehicles' satellite navigation and mapping systems have also been down.
Call handlers have had to write 999 details by hand, rather than using a computer dispatch system.
An ambulance service spokesman said patients affected by Wednesday's disruption were being informed and planning was in place for Thursday's transport arrangements.
People should contact their normal treatment clinic for appointment queries.
