When parts of the server framework are turned off or changed significantly, it would be cool to get a head up in advance.
While these changes might only take 5 minutes, it is still nice.
=> A nice side effect is, that it boosts the communities morale. Seeing progress and changes is good.
When changes to the auth and verification server (which the client uses) are made, this must be announced, since there chances are very high that someone in that moment will notice it.
