Virgin Media customers across the UK were left without broadband access on Tuesday July 1st following a Domain Name Server (DNS) outage.
A number of customers took to social media complaining they were unable to connect to the internet and access some websites.
The outage follows a similar problem experienced by BT at the weekend, and an earlier DNS issue reported by Virgin Media customers on Friday June 27th.
Broadband providers use DNS to translate internet addresses into human readable form. In the event of a server error, users may not be able to load web pages.
Gareth Mead, a Virgin Media spokesperson, told PC Pro that the company was "sorry" for those customers affected by the outage.
He noted that some users experienced only intermittent access to certain websites for approximately an hour.
"It was quickly fixed although changing DNS settings in the interim would have solved the problem," Mr Mead noted.
