Sainsbury's online store crashed for the second time in weeks
over lunchtime on 4 July, according
Keynote Systems, a specialist
in software as a service test and measurement solutions.
Keynote reported that Sainsbury's website was unavailable from
12.45pm to 2.10pm BST on Friday 4 July.
Visitors to the third largest UK retailer's website were unable
to see the homepage, while its main competitors - including Tesco,
Asda, Ocado, Iceland and Waitrose - remained open.
The outage follows a two-day service disruption caused by an
internal glitch that is estimated to have cost the retailer £1.5m
in lost sales and compensation.
"Following Friday's outage, the homepage was taking
approximately 20 seconds to load, in comparison to competitor
sites, which were all taking less than four seconds," said Martin
Stern, regional manager EMEA at Keynote Systems.
