You can view the status of your machine through your mining pool dashboard. Furthermore, all facilities have technicians on hand to address momentary hiccups. Compass both monitors machine uptime and maintains close communications with hosting facilities to keep machines running.
Machines may appear offline or be moved offline for a brief period of time depending on the specific needs of the machines or the facility. For example, many ASICs overheat and must be powered down momentarily to cool before being turned back on.
Tickets can be submitted to the Help Center for machines that remain offline for an extended period of time. Please only submit tickets for an offline machine after four hours of inactivity.
