York Data Centre

YO26: Bytemark's own data centre

YO26 is our very own data centre in York.

YO26 has been designed and built completely to our own technical specifications and business requirements. We control every single aspect of the service — from the land, to the power, network, and servers.

Our ownership of the whole project means we can stand behind the data centre’s stability. So you can trust us to deliver the best possible service without having to deal with multiple suppliers.

For customers needing multi-site availability we also have data centre space in Manchester.
