Black Friday crashes John Lewis website

John Lewis’s website crashed for about an hour this afternoon as it experienced “record levels” of demand for its Black Friday deals.

The site was down between 3pm and 4pm. The retailer said: “There are record levels of demand for our website today and for some people it is taking longer than normal to shop on We apologise to customers for any inconvenience caused.”

IT firm Capacitas estimated that the outage could have cost John Lewis up to £2.8m in lost revenue.

“This down time is undoubtedly expensive for John Lewis,” it said. “They report annual online revenues of £1.4bn and we typically see 2% of annual demand taking place on Black Friday.

“In addition 10% of the Black Friday day’s sales typically take place in the peak hour. This means an hour of downtime on the John Lewis website could amount to £2.8m in lost revenue.”
