The BBC’s websites have broken, making one of the biggest news sites in the world unavailable.

The BBC’s breaking news Twitter account said that its website was “currently experiencing some technical issues”. It said that its team was “working as quickly as possible to resolve them”.

It made no mention of bbc.co.uk — the corporation’s main site — though that also appeared to be inaccessible. The iPlayer online video on demand service was also experiencing problems, according to Downdetector.

Visitors to the affected services were just shown a message saying that the site could not be accessed. Some of the sites appeared to load but never actually showed any information.

None of the official BBC channels made any statement about why the site had gone down, whether it was an internal or external problem or whether the issues had been caused by anybody else.

The BBC’s main website is the 89th biggest in the world, according to Alexa. It is the seventh-ranked site in the United Kingdom.
