Sports clubs and broadcasters are among those affected by a worldwide IT outage.

Manchester United said they were postponing the release of tickets due to the outage and that the club’s website was down until the issue was resolved.

Sky Sports News was unable to broadcast live and was directing viewers to its app and its website.

Overnight, Microsoft confirmed it was investigating an issue with its services and apps, with the tech giant’s service health website warning of “service degradation” that meant users may not be able to access many of the company’s most popular services, used by millions of business and people around the world.

EFL clubs including Blackburn, Bolton, Bradford, Chesterfield, Huddersfield, Leyton Orient, Lincoln, Plymouth, Preston, Rotherham and Walsall were among the first to report issues.

Scottish top-flight clubs Hearts and Hibernian also posted to say they had been affected by the outage.
