The property directly north of that one is also a miniature datacenter/telco hub. You can see the 3 phase power power feeds and extensive fiber cabling from the street. Has a similar exterior look with fake windows and a hazmat sign on the gate (which presumably is for the diesel or fire suppression system). They both look like McMansions compared to the surrounding homes and stick out as this part of Dallas isn't the most affluent. AT&T used to this property. Not sure about the adjacent one.
