EFTPOS down Brisbane

Shoppers were left unable to pay for trolleys full of groceries, while websites and servers crashed around the nation in a spate of technical outages on Sunday.

Amazon Web Services, which hosts cloud computing services for many companies, listed a number of connectivity issues for its services based in Sydney. It is not yet known whether the storms that lashed Sydney over the weekend were responsible.

Some of the websites affected include those belonging to Fairfax Media, publisher of this website; Foxtel and Fox Sports; car sharing service Go Get; The Daily Telegraph's NRL Super Coach site; Nine and Fairfax-owned online streaming platform Stan; ticketing platform TryBooking; and online food ordering service Menulog.

Meanwhile, a separate technical outage caused numerous financial services including debit cards, ATMs and Eftpos machines to fail on Sunday night.

An AWS spokesman said the problem was not related to the website issues with Amazon Web Services.

Customers from Westpac, Commonwealth Bank and ME Bank complained on the companies' Facebook pages, with some saying their eftpos payments did not work.
