The Department of Health has said that work is continuing to restore the essential work of the department as quickly and as safely as possible.
Many systems remain affected and offline.
Currently, correspondence, either electrical or postal, is unavailable and there is no service currently for processing Freedom of Information requests, or Parliamentary Questions.
The Department has said that as email is restored, there will be a significant volume of correspondence for processing, against the backdrop of continued limitations, due to the impact of the cyber attack and Covid-19 and this will take time.
The cyber attack on the Department of Health occurred on 13 May, the day before the Health Service Executive was hit.
