If you are a Nuvolat end customer and own or lease one or more servers that reside within a CoreSite data center or are a leasing company or secured creditor with a lien on a server located within a Nuvolat space, and wish to take possession of servers, CoreSite is aware and monitoring the evolving situation involving Nuvolat Cloud Group (“Nuvolat”).

In our role as landlord, CoreSite is limited in what we can do under relevant contracts, but we have dedicated the past two weeks to providing whatever support we can to assist Nuvolat customers in obtaining possession of customer-owned hardware. We have had very limited communication from Nuvolat regarding the state of its business, which has made it extremely difficult to connect customers with their hardware.  

Please be aware that CoreSite has not designated any specific partner to support the identification and retrieval of Nuvolat customer property. In addition, we are, unfortunately, restricted in our ability as landlord to act any further. If you need support with a colocation solution, please complete the contact form.
