At 5:13am this morning we saw a brief power event on our main UPS in BOL8 datacentre followed by Switch DS-105 going offline.
Although no issues are reported surrounding the power event, any customers directly connected to switch DS-105 are currently offline.
DS-105 is a legacy switch stack and not part of our newer core network.
Customers connected to other switches are unaffected.
An engineer has been dispatched to investigate.
