A network problem caused all BBC online news websites to suffer a complete outage for an hour.
The BBC confirms users were unable to access its websites until midnight on 29 March after experiencing technical difficulties.
In a blog post, Steve Herrmann, editor of the BBC news website, wrote: "It's not often we get a message from the BBC's technical support teams saying there's a total outage of all BBC websites."
"But for getting on for an hour this evening, until just before midnight, that's what happened. We haven't yet had a full technical debrief, but it's clear it was a major network problem," said Herrmann.
"We'd like to apologise to everyone who couldn't get onto the BBC News website during that time," he added.
The BBC recently announced it is moving to the cloud as a key part of its new technology strategy for consuming IT services.
Internet data on site traffic shows the BBC was offline for one hour and eight minutes at 22:39.
