Services from media to healthcare have been affected by the global Microsoft issue.
A spokesperson for Castle Healthcare on Wilford Lane in West Bridgford said:
‘We are aware of a global IT issue which is affecting some primary care services in our region.
‘It may be necessary for GP practices to rearrange appointments as they manage this issue. If you have an appointment booked you should attend as planned unless you are advised otherwise.
‘Work is ongoing to resolve the issue as quickly as possible.
‘Those who need urgent medical care should call 999 or attend A&E, especially in emergency and life-threatening cases when someone is seriously ill or injured, or their life is at risk.
‘Please use NHS 111 online for all non-emergency healthcare needs.
‘More information about when to call 999 and when to go to A&E is available via the national NHS website.
‘Further updates will be provided on the practice website as soon as they are available.’
