A broadband company has apologized after its customers reported widespread problems accessing Internet services in the Republic of Ireland.
Eir said it was "a widely used DNS known" [Domain Name System] Failure that affects some customers in both our landline and mobile networks. "
The company said its engineers "worked to solve this problem as quickly as possible".
Several customers have complained about missing information about the error.
Many contacted Eir through their Twitter account to criticize the company's customer service and did not specify how long it takes to fix the problem.
BBC News NI contacted the company to receive a response to the criticism.
Eir, formerly Eircom, offers broadband, mobile and fixed line services as well as TV packages.
