When to use this email
An outage is happening right now and customers are likely affected
You want to get ahead of the support tickets with a proactive notice
You need to point everyone to one source of truth for updates
Reassuring customers you're already working on it will reduce panic
Tips for making it yours
Send it fast. A quick "we know" beats a polished email an hour later
Separate what's broken from what still works so people aren't guessing
Give an honest ETA or say you're still investigating. Don't invent a time
Point to one status page link so you're not answering the same question 50 times
