*Costs savings are based on CoreSite cost comparisons using publicly available and private information and/or CoreSite customer reported costs savings and may not be indicative of the costs savings that may be experienced by every customer that switches to the applicable CoreSite service.

**Calculations based on speed tests conducted by CoreSite of direct interconnection product vs. the public internet and may not accurately reflect your performance improvements. These tests have not been independently verified by any third-party and should not be deemed to be an assurance or guarantee as to expected performance.

“The inter-site connectivity between the NY1 and NY2 CoreSite facilities was a key component in our decision because it meant we’d never go down. But the ability to connect with a huge variety of carriers between the facilities, providing flexibility, coupled with the office space and impressive resources of the site really sold us.”
