An operational notice says that something is not as it should be: an interface is down, a maintenance window is approaching, a message queue has built up. The value lies in the order of events. Arriving before the recipient notices the problem, it is information; arriving afterwards, it is an apology. In the market processes this is more than courtesy: many processes have deadlines, and a party who knows the ElhubNational hub for metering data and market processes in the Norwegian electricity market. interface is down for two hours can choose to postpone a submission rather than burn its retries. Notices that are precise about what is affected and what is not spare the recipient from investigating. Notices that say only that there are "technical problems" move the work onto whoever reads them.
