University Hospitals Sussex NHS Foundation Trust said a global IT outage disrupted its systems on Friday 13 November 2026, stopping email at 10am and leaving some services running more slowly for the rest of the day.
The Trust, which runs hospitals including the Royal Sussex County Hospital in Brighton, linked the problem to ongoing Microsoft IT problems affecting organisations worldwide. It said the outage began on the night of Thursday 12 November.
What the Trust said happened
10am. The Trust said it was still assessing the impact on its services and systems, and that email could not be sent or received. It promised updates.
Later on Friday. Some services were running more slowly. The Trust's update did not name particular hospitals or services as affected.
Afternoon. Email services began returning during the afternoon, although some services were still slower than normal.
5pm. The Trust thanked staff for managing the day's disruption and thanked patients for their patience.
What patients were told
The Trust's advice in its patient update was to keep attending appointments as planned unless told otherwise, and to keep using Trust services as normal. It asked people to be patient and to use services only when necessary. Anyone unsure what to do was pointed to NHS 111 or 111.nhs.uk.
The page does not say whether every appointment went ahead.
Where things stand
The Trust said it hoped recovery would continue into the weekend and that it would post further updates on its website and social media as needed. At the time of writing we have found no later update on the Trust's website. Check the Trust's website or social media before travelling if you have an appointment this week.
