Tesco’s website and app was targeted by cyber attack in October 2021.
Their online grocery store website and app were interrupted.
There have been issues with the site's search feature as a result of an attempt to meddle with their systems.
They apologise for the inconvenience and worked very hard to fully restore all services.
