Transformative Impact with 100% Uptime

I like how CoreSite makes it easy to centralize everything and keep things tidy. Their menu design is quite good. As a deliverable, the platform stands out because it radically simplifies high-speed, direct interconnection and reduces network complexity. CoreSite builds highly dense, network-rich facilities in major metropolitan markets, allowing us to scale our footprint within the same facility. They helped us implement VMware vSphere for our private cloud virtualization, integrated with Veeam for high-speed backup and disaster recovery, and facilitated the setup of Cisco virtual routing software to manage our connections through the Open Cloud Exchange (OCX). This led to a 40% reduction in network latency and significantly improved system uptime. What we like most is their 100% uptime reliability and the absolute ease of scaling our bandwidth on demand using OCX. Their customer support and engineering teams are highly responsive, which makes infrastructure management predictable.

Highly reliable data center with excellent multi-cloud connectivity

The physical security and operational uptime are absolute top-tier. I rarely have to worry about power redundancies or cooling issues. Their customer portal is also incredibly intuitive for cross-connect provisioning, and the remote hands team on-site is fast and actually knows what they are doing when we need a physical drive swapped or a cable re-routed.
