Sainsbury's web site back up and running

The online arm of the supermarket chain took over 48 hours to fix the web site glitch

Sainsbury's glitch has affected some 20,000 online shoppers

Sainsbury’s online ordering system is up and running but customers left without groceries over the period it took to fix the problem will have to wait until Saturday before the delivery service resumes.

The chain’s online operation was unavailable for just over two days due to a " technical glitch" which is thought to have affected around 20,000 customers.

In a statement, Sainsbury's said: "we have spent just over 48 hours fixing the problem and the web site has been thoroughly tested."

Customer information remained safe and the possibility of a hacking attack was discarded by the supermarket chain.
