This morning at approximately 7:00am central time, we experienced a power failure in our cabinet at our datacenter, causing loss of connectivity to our servers.  This issue was caused by a severe increase in power consumption by some of our equipment, causing our power distribution unit to shut down due to more power being drawn than it could handle.

Connectivity was restored at approximately 8:15am and all gateways are functioning properly at this time.

We’re investigating the cause of the increased power usage and have an order in for a PDU that will handle larger power loads in case of situations like this.  We will need to take a short planned maintenance when that new PDU arrives in order to install it.

As some of you may remember, we experienced a similar issue in May.  The unit we experienced the issue with in May was replaced by our datacenter technicians with a new PDU of the same make and model that was in stock as a replacement part.  We had determined at the time that the PDU itself likely had a problem, which was why we replaced it.
