Visitors to Number 10 TV site were greeted by an error message
Prime Minister Gordon Brown's new website has been hit by teething troubles, Downing Street has confirmed.
Number 10 TV was officially launched as part of Mr Brown's efforts to reach out to a wider public.
The site will feature exclusive video coverage of the prime minister's speeches and media appearances.
But anyone trying to access it was met with a "404 page not found" error message. A Downing Street spokeswoman denied the site had crashed.
But she said users on some servers might experience glitches "for the next 48 hours".
"It is just what happens when you launch a new website," she added.
Number 10 TV is part of a redesigned Downing Street website, which includes news, guided tours of Number 10 and official reports.
Downing Street says the revamp is designed to "boost the amount of video content".
It comes two years after Conservative leader David Cameron launched his own website, Webcameron, which regularly features behind-the-scenes content.
In May Mr Brown launched an online version of prime minister's questions.
He pledged to respond to video-clip questions submitted via the Downing Street Youtube website.
