Located in the middle of Mexico, Querétaro is a charming and colourful colonial-style city known for its dazzling stone aqueduct.
But the city, and state of the same name, is also recognised for a very different reason - as Mexico's data centre capital.
Across the state companies including Microsoft, Amazon Web Services and ODATA own these warehouse-like buildings, full of computer servers.
No one could supply an exact number, but there are scores of them, with more being built.
Ascenty, which claims to be the largest data centre company in Latin America, has two in Querétaro, both around 20,000 sq ft in size, with a third under construction.
