The data centre also incorporates VIRTUS' real-time monitoring dashboards, and self-service tools for customers to use either remotely, or in one of our dedicated customer offices, kitchen or touchdown areas that are designed into the facility.

The facility is carrier neutral and provides access to a wide choice of Tier I and Tier II carriers, and on-ramp access to all major cloud and connectivity platforms.
