Tesco’s website and app are up and running again after a suspected hack.
The outage, which left customers struggling to shop for groceries or track orders, began on Saturday morning and continued into Sunday.
The supermarket chain said it was experiencing “major disruption” following “an attempt to interfere with our systems”.
In an updated statement on Sunday, Tesco said: “Our online grocery website and app are now back up and running.
“Our teams have worked around the clock to restore service, and we’re really sorry to our customers for the inconvenience caused.”
Problems first arose when customers reported they were unable to place, amend and finalise orders, or track active deliveries.
Tesco said there was no reason to believe customer data was affected.
An initial statement from Tesco said: “Since yesterday, we’ve been experiencing disruption to our online grocery website and app.
“An attempt was made to interfere with our systems which has caused problems with the search function on the site.
“We’re working hard to fully restore all services and apologise for the inconvenience.
“There is no reason to believe that this issue impacts customer data and we continue to take ongoing action to make sure all data stays safe.”
Shoppers took to Twitter to vent their frustration at the lack of information and support while Tesco’s systems were out-of-action.
One user wrote: “I’ve got a shop being delivered tomorrow but I’ve not added all my items to the shop yet! What am I supposed to do if I can’t amend the shop ?”
In response, another said: We’re in the same boat, if I can’t edit it before the cut off my vulnerable mum will be receiving the place holder items we added when booking her usual slot rather than her actual shopping list she’s sent me today. Fun times!”
“I’ve been charged £20 for the few bits I had in my basket plus a delivery charge. My delivery is also late as my slot was 8-9 this morning. Got to laugh or I’ll cry,” added a frustrated customer.
