The websites of the BBC were taken down Thursday following a large-scale cyber attack.
Citing anonymous sources, the BBC said a DDOS — denial of service — attack was to blame.
A Twitter account managed by the BBC’s communications team claimed the outage was due to a “technical issue.”
Hackers use DDOS attacks to flood a website with so much fake traffic that it disrupts normal service.
The BBC’s website outage lasted for nearly four hours before service was restored.
Social media users reported that the broadcaster’s popular iPlayer catch-up television and radio services were also down early Thursday.
BBC News is one of the world’s most visited news sites.
Before service was restored #BBCdown was the second most popular Twitter hashtag in London as users complained about the extended outage.
