Please note that the outages will be in no particular order. Do not expect them to follow the order in the list.

The reason for these outages is that we're re-cabling some of the networking in our data centre. Each machine will be unplugged from its old network cable, re-terminated onto our new frame, and move to a new port on the core switch. This will entail reconfiguring ports on the switch.
