THE Royal Family is kept online by super computers stored in an unassuming Croydon industrial unit, it has emerged.
Pulsant, based in Imperial Way, was this week granted the Royal Warrant as provider of hosted IT and data centre services to the Royal Household.
It joins an exclusive club boasting household names likes Coca-Cola, Aston Martin, McVities biscuits and Strongbow cider.
The company was this week tight-lipped about its involvement with the monarch's data.
And asked whether the Queen's private e-mails were stored at the site, its chief executive Mark Howling refused to comment.
He said: "Obviously, we cannot divulge a lot of what we provide to Her Majesty's household and that professionalism is part of how we have built our reputation.
"Royal warrants are rare and highly respected for recognising the highest standards of service, excellence and quality.
"Our Royal Warrant cements our commitment to delivering world-class data solutions and services."
Buckingham Palace has long refused to comment on the Queen's private electronic communications.
But the Queen is said to have let slip that she had an e-mail address and reportedly told the editor of Vanity Fair magazine at a garden party that she dictated them to a member of staff.
Our monarch is not yet on Twitter. However there is an online presence in the form of twitter account @BritishMonarchy.
There are also several popular parody accounts, one of which (@Queen_UK) has more than a million followers.
Pulsant serves more than 3,000 customers and sources all of its energy from renewable sources.
Paul Hughes, head of marketing and product development, added: "We are very honoured and it just shows what the company offers.
"To receive this from someone of the Queen's stature is astounding."
