Is the instance by sector, block sector or the whole galaxy?
instance is the map area your in which is also refered to as zone there are multiple zones or instances housing the same map area, there maybe as few as two or three zones\instances per area depending on the number of players accessing the same area.
each area or map has its own zone chat. sector space or system space and planet or starbase each has its own map which has its own zone chat.
zone chat only displays chat for the zone\instance in it dosent display chat from any surrounding zones or other regions
zone chat channel speaks to all zones\instances for the map area your currently in regardless of how many there are
local chat channel speaks only to the zone\instance your currently in not any other zones that may exist for your current area
iirc you can see which zone your in in your character info also when you click on the change zone either from the map or the location title above the minimap\radar

ive not heard of any gamewide chat channels, only ones that may exists are user created channels
other than that the fleet channel reaches server wide but only for your fleet
