Tonight's 10 million euro lotto jackpot draw has been postponed due to a service outage.

Thousands of people have been unable to buy lotto tickets today as 3,500 ticket machines have been out of action since this morning.

The National Lottery have confirmed that there were technical problems with the machines following a 3G telecommunications service outage.

In a statement, they say they're working to re-establish the network connection, and to ensure everyone has an opportunity to play, tonight's Lotto draw will now take place tomorrow instead.

Tickets already purchased for the midweek draw will still be valid.
