State what changed since the last report, the time and zone, and the exact feature affected. Then give the next action appropriate to the audience: retest a specific step, avoid duplicate submissions, or provide a safe comparison.
Separate confirmed facts from possible causes. “The login page returns an error on two networks” is evidence; “the authentication database is down” is speculation unless verified. If service recovered, describe the test that passed and whether you will continue monitoring.
A short update should answer “what is true now, and what should I do next?”
