• Full recovery from largest IT outage in history' could take weeks

Britain's Sky News is back on air after an outage lasting several hours, but its presenter said the news channel was operating at minimal capacity and without many of its usual services.

Two presenters were reading from paper scripts, with one, Anna Jones, saying they were not yet able to connect to any guests outside the studio to conduct interviews.

We're impacted by the IT outage. This will have a big effect on us, so apologies in advance for the inconvenience caused, and delays on the phone.

Due to ongoing Windows issues affecting IT worldwide, the practice is currently unable to function as normal.

This may result in appointments needing to be cancelled and rearranged. Updates will follow when available.

All practices in the UK using the NHS commissioned GP computer system EMIS are currently without access to their IT systems.
This is beyond the control of GP surgeries. Please bear with us until we have our IT systems back online.

We have no access to patient clinical records so are unable to book appointments or provide information... This is a national problem and is being worked on as a high priority.

Unfortunately there is a national issue with EMIS Web - our clinical computer system.
This will affect our ability to book/consult with patients this morning.
We will update patients when we can. We apologise for the disruption.

I'm currently sat in NHS Chorley Hospital (UK) and can confirm they are having issues and have been told they maybe cancelling appointments. I am an outpatient.
