Max, alone on the night shift, follows a red ring to the website customers use, checks whether it is the planned storage work and hands Irina's day team an honest record at 7:00.
Night shift / NOC
Max works nights on the monitoring desk of a delivery company: the people who watch the servers around the clock (IT people say NOC, a network operations centre). He is alone until 7:00. Before leaving, Irina from the day team wrote in the chat: “storage work tonight”. At 01:30 a server in the data centre turns red. Is this the planned work? What stops because of it? Whom should Max wake?
On the map a server in the data centre wears a red ring. Max does not guess. He asks AverDesk what sits on top of this server, and it walks up the chain for him (the impact view: host, service instance, service, product). Three things depend on it. One of them is the website where customers track their parcels.
Each service’s card works as up-to-date documentation: which ports it uses, which outside systems it talks to, where its backup site is. The responsible team is written on the card too. Max opens an incident (INC), a record of the fault, and the alert goes to that team in the app, by email and in Telegram. If the same alert fires again, it stays quiet instead of ringing again.
The maintenance calendar shows work on the storage system from 02:00 to 04:00. That is thirty minutes away, and it is a different device. When the work begins, the storage will wear an orange ring; the server that just failed wears a red one. Now Max knows two things: this fault was not planned, and in half an hour the services above the storage will go into maintenance as well.
The storage team starts at 02:20, not 02:00. AverDesk records the real time next to the promised one and recalculates what is affected. A group of services shows the worst status among its members, so the parcel website shows “maintenance” for exactly as long as the work really lasts.
Irina arrives and reads the incident’s history instead of a sticky note. The availability page shows the night as it was: the current state and a bar for the last 90 days. A day when nothing was checked stays an empty gap on that bar and is never painted green by default. The morning report says exactly what was watched and what was not. Max goes home.
