"Digital Realty has posted an announcement outlining the potential impact Sungard's situation could have on its financials. While it didn't name the company explicitly, Digital Realty recently noted 'a privately held IT service provider' declared bankruptcy on April 11.
DR said the company is its Digital Core REIT's fifth-largest customer, occupying 2.7MW of capacity in Toronto and representing approximately $5 million of annualized revenue; around 7.1 percent of Digital Core REIT's total revenue. Sungard has paid its rental obligations for April and has said it intends to keep paying suppliers.
The same customer is also Digital Realty's 23rd largest customer and leases approximately 10.5MW directly from Digital Realty across six facilities in four markets, totaling approximately $22 million of annualized revenue, or 0.7 percent of Digital Realty's total revenue.“
