Take advantage of US Signal’s colocation facilities to help meet your DR needs. 

Cold site

A bare-bones approach to DR, a cold site is the least expensive DR site. It has the basic infrastructure needed to run a data center, such as network connectivity and power, but little else. If a disaster occurs, the equipment needed to restore service must be procured, delivered, and configured. As such, the use of a cold site can make for a lengthy recovery period.

Warm site

A warm site provides the same infrastructure as a cold site, but has hardware and connectivity already built in — typically on a smaller scale than the original production site or a hot site. Recovery time is quicker than with a cold site, but some lead time is required to bring servers online. Network connectivity must be established and then data must be transferred to the warm site.

Hot site

A hot site is a duplicate of your data center. It is the most expensive option but offers the shortest recovery time and is recommended for mission-critical data. A hot site can typically be up and running within minutes to hours, resulting in minimal impact and downtime to operations. Personnel may need to move to the hot site, but the hot site may be operational from a data processing perspective before staff has relocated.


US Signal colocation facilities can be used in an active-active configuration to create a continuously available solution. Network technology is stretched between two sites. The storage platform is virtualized across the two sites to create a data presence that is mirrored between the sites and allows concurrent write-access in both. Applications can operate in both locations and data is synchronized in real time.
