When something breaks, customers want to know three things: is it just me, are you on it, and when will it be fixed. A status page answers all three without a single support ticket.

Post a short update early, even if all you can say is that you are investigating. Then update again when you know more. Clear, regular updates feel professional even during a bad day.

Planned maintenance belongs there too. Announce it a few days ahead and subscribers get an email.
