Looks like bank of irelands network might have gotten busted somewhere.
There's a thread here:

anyway, it looks like their ATMs might go out of order while their engineers are fixin the issue
so, don't be left stuck.
if ye only got access to a BOI atm, then wander into their branch before they close (prolly 4pm) to get some money.
or maybe you are in work but only got access to a BOI atm at home... then if you plan on needin cash there... get it out now
that is all... move along, nothing to see
Mod note :
(1) Tempting thought it might be ... there is no such thing as free money
(2) We can be sure the ATM's will have a local record of each transaction / amount / account details.
(3) If & when BOI reconcile the ATM transactions they will know the cards/accounts matching the withdrawals.
