Many of them across the UK have been cut off from Facebook. A DNS issue is causing a huge problem for a large number of Virgin Media's 5 million customers to lose the access to Facebook.
The site will be unaccessible until 15:40BST. Both the Instagram as well as Messenger are also understood to be affected.
Now, Virgin has blamed Facebook's issues. Virgin Spokesman said that "We’re aware of an intermittent issue that’s affected some of our broadband customers accessing Facebook and Instagram. We believe this was an issue with Facebook’s servers, which we understand to be resolved. We’re contacting Facebook to confirm our customers can now access these sites.”
It is a technical issue called DNS (Domain Name System) error is to blame. This basically stops the web address from working properly, means that people can't access it.
The company released a statement that they are aware of the issue and are working on a fix with the plans to restore full access to social media before 4 pm on April 12th. In UK time, it will repair by 9.35 pm.
