Write the outage update while you fix the outage
Pick where you are (investigating, identified, monitoring, resolved), say what customers see and when the next update is due. You get the status page text, a customer email, a short post and, once it's over, an outline for the write-up. Plain words, a time zone on every time, and a line about data, because that's what people worry about first.

Where are you?
You see the symptoms, not the cause.
What's happening
Times
Put the time of this update (HH:MM). Every update needs a time with a time zone.
When did it start? Customers check whether their failed attempt was part of it.
Copy this
Investigating - [time] UTC Some customers are having problems with [Product]. We are looking into it now. Data you had already saved is not affected as far as we can tell. Next update within 30 minutes.
Before the next outage
Put the status page on hosting that doesn't share your servers, turn on email subscriptions, and keep an export of every customer's admin contact outside the product. Decide who writes updates while someone else fixes. The first update goes out within half an hour, even if all it says is that you are looking into it.
The timeline, what Atlassian, Cloudflare and GitLab did in public and how to handle credits are in our article after the outage: what a small SaaS publishes, and when. For what buyers ask about incidents before they sign, see the security baseline check.
