A massive IT outage has affected grocery stores, retailers, and fast-food giants around the world.

Australian grocery-store chain Woolworths told Business Insider that some stores had "been impacted as a result of the global IT issue." However, all but six stores were open, while some had fewer checkouts functioning.

A banner on Woolworths' website says that it's "experiencing intermittent technical difficulties instore and online."

Coles, another Australian grocery-store chain, told BI it was being "affected by a global technical issue which is disrupting some of our systems in our supermarkets and liquor stores."

A spokesperson told UK grocery-store chain Morrisons told BI that it was "experiencing some issues with payment in some stores."

Social-media users said Waitrose, an upmarket UK grocery-store chain, was only taking cash payments because card machines weren't working.

Bloomberg reported that at the Ocean Park Marriott in Hong Kong, staff were using pen and paper to check guests in and had said that the outage was affecting its systems globally.

Major airlines, banks, and supermarkets are experiencing widespread disruptions linked to an IT outage after Microsoft reported problems with its online services, linked to an issue at cybersecurity firm CrowdStrike.

But not all retailers have been affected. Representatives for UK grocery-store chains Asda, Sainsbury's and Marks & Spencer told BI that they were operating as normal.
