We strive to be a responsible steward of our business for all our stakeholders.

Message from our CEO

Customers. Colleagues. Communities. These three words describe the symbiosis of our business strategy with our sustainability practices. Since 2001, CoreSite has been committed to providing best-in-class customer experience and value, an engaging, attractive and diverse employment environment, and practices that help our customer communities thrive sustainably.

2020 proved to be challenging for all of us. I’m excited to report that our team overcame these challenges by executing on our strategy and prioritizing the safety, satisfaction and general welfare of our customers, colleagues, and communities. We quickly responded to the ongoing pandemic. Our data centers have remained open and fully operational with essential staffing, personal protective equipment and sanitation, world-class air filtering and social distancing measures in place. We maintained very high uptime, significantly exceeding the industry standard, and successfully enabled numerous customer expansions and implementations.

Today, more than 1,375 customers rely on us to efficiently power, protect, and interconnect the servers that drive their performance-sensitive data applications and computing workloads and deliver their data products to their customers.

Over the past few years, we began to track more systematically and report key sustainability markers. To guide this effort, we identified the issues that matter most to our stakeholders and to us. Here, in our fourth Corporate Sustainability Report, we summarize our ongoing journey of being a responsible steward of our business.
