MA1 is a data centre in Manchester run by Equinix, who gained it on acquiring its former operator Telecity.
The data centre was original built for the University of Manchester, who spun it out under company Internet Facilitators Limited (IFL). IFL was acquired by Telecity which was itself acquired by Equinix.
The data centre is in Manchester Science Park. There are two L-shaped buildings: Williams House and Kilburn House. MA1 runs through both.
