Virgin Media has apologised to customers after they were unable to access Facebook and Instagram.
The problems, arising from an issue with the operator’s DNS system emerged on Tuesday evening and continued into Wednesday afternoon.
“We have now investigated an issue which meant some Virgin Media customers were intermittently not able to access Facebook and Instagram,” said the operator.
“This was due to an interconnect router going down on Virgin Media’s network meaning that some of our DNS requests were not able to contact Facebook servers.
Our fault has now been fixed and we apologise for any inconvenience caused.”
