Question: If NSFW is down, then how can a user
identify it?
Answer
If NSFW is down, then the notification service generates a heartbeat alert. And, a heartbeat alert gets closed once NSFW is up.
There is a delay of 5 minutes for the alert to generate because NSFW is sending the heartbeats every 5 minutes. If NSFW is
down for a longer period, then the last updated time of the heartbeat alert gets updated instead of creating lots of alerts.

that alert, and user can move onto the next.
