Eircom can't say when full service will be restored as thousands of people affected

Eircom said they had not yet identified the cause of the intermittent problem and technicians were working to resolve it.

Dublin Fire Brigade has tweeted to say it has been advised by Eircom that using landlines to contact emergency services may be difficult.

We are advised by #eircom that using landlines to contact emerg servs may be difficult. Some mobiles also affected. This is a national issue

Assistant chief fire officer with Dublin Fire Brigade Denis Keely said: "The first point of contact is from their mobile phone or from their housephone because it is an intermittent issue. Our understanding is the 112 and 999 numbers are ok."

Childline has also tweeted that children trying to use its service may be experiencing problems.

Customers cannot call the Eircom customer care centres so are being advised to report the fault online.

Director of Corporate Affairs at Eircom Paul Bradley said: "We're working as hard as we can to identify the root cause and get the full service restored as quickly as possible (but) I can’t give an estimation as to when full service will be restored."
