Estate agents have been among those hit by an IT accident at the weekend, which took down their websites and left them with empty email boxes.

UK hosting and domains provider 123-Reg, whose 800,000 UK customers are mainly small businesses, accidentally took an unspecified number of its customers’ websites down during maintenance on Saturday morning.

The company subsequently told customers that some data was deleted, and some information lost permanently.

While some customers have been able to restore their websites through their own back-ups, those who backed up their data with 123-Reg have been unable to do so.

Among those affected was Cooke & Co Kent whose website was still not working yesterday morning, although the firm tweeted out that this would shortly be put right.

While its site and back-up were both deleted, the firm also has off-site back-ups.
