*Optionally, in the case of server overload, this message can be sent without CUE branding or not at all (i.e.: The 503 status may be sent with an empty document body, or no response may be sent). A defensive position against Denial Of Service attacks might be to not respond to incoming HTTP requests for a period

**Optionally this text can be replaced with a specific date and/or time (specifying AEST) that it is expected the resource will become available again (in which case a Retry-After header should also be used).
