Zulip Delivery and Login Outage Checklist

Narrow down a Zulip communication failure

Check the Zulip status page before changing organization or bot settings.

• Compare web, desktop, and mobile sign-in behavior.
• Test message send, receive, and notification delivery separately.
• Ask whether one realm or multiple realms are affected.

Do not resend automated messages in bulk until delayed delivery and duplicate-post risk are understood.
