The Irish Health Service Executive has shut down its IT systems after being classified as a “major ransomware attack”.

“As a precautionary measure, we shut down all of our IT systems to prevent this attack and to be able to fully assess the situation with our own security partners. “

The HSE added,” We apologize for the inconvenience this may cause patients and the public and will provide further information as it becomes available. “

The Rotunda Maternity Home in Dublin had to cancel many routine appointments due to IT problems.

” Due to a serious IT problem, all outpatient visits are canceled today – unless you are 36 weeks pregnant or later, “the hospital tweeted.

In a tweet, the hospital added,” If you have an urgent concern, please attend as usual. “
