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.

Unmatched Reliability with Outstanding Low Latency Connectivity

I really like CoreSite's unmatched reliability with 99.99 percent uptime, and their expert remote support is top-notch. I appreciate the reliable, well-maintained infrastructure that offers strong redundancy and security, which is critical for us. CoreSite enables outstanding low latency cloud connectivity which is essential for our needs. Their Open Cloud Exchange and rich carrier system allow us to establish direct, low-latency connections to cloud services like AWS and Azure. This has led to measurable gains, such as improved business applications and a better end-user experience with fewer support tickets for slow internet. What really sets CoreSite apart for us is their tailored high-density infrastructure and support which meets our digital learning demands. They have a proprietary technician qualification program, methodical project management for deployments and migrations, and high-density interconnection capabilities. During a major redevelopment of our AI-enhanced genomics research platform, their team enabled seamless hybrid cloud bursting and maintained 99% uptime during peak semester loads, improving efficiency and allowing our IT staff to focus on innovation rather than maintenance. CoreSite's team provided invaluable remote hands and expert guidance during the implementation of our high-performance software stack, including NVIDIA GPU-accelerated environments, which minimized downtime and improved operational efficiency, research output, and student success metrics.
