A number of Government websites are back up and running following a cyber attack.
Hackers took down the Oireachtas site as well as the Courts Service, Department of Justice, Department of Defence and the HSE.
It's believed they were targeted by DDos attacks - which overwhelms sites with traffic from multiple sources.
The sites were off-line for a number of hours but are back now.
The National Lottery suffered a similar attack earlier this week which affected its website and game machines for two hours.
