I didn't get an alert — what happened?

Most "missing alert" reports fall into two buckets: a delivery problem, or the system working as intended. Run through these in order.

Delivery checks

• Look in spam, and add our alert address to your contacts so future emails land in the inbox.
• Is the channel enabled and correct? A disabled, deleted or mistyped Slack/Telegram/Discord/webhook channel silently drops messages — re-send a test.
• Is the monitor enabled, with the right checks turned on?
• Is the workspace active? A non-personal organization without a live paid plan is locked and won't run checks.

Working as intended

• Brief blips don't page you. An outage that recovers before quorum is reached is suppressed on purpose — that's the anti-noise design, not a miss.
• Expiry fires once per threshold. If you already got the 14-day warning, the next one is at 7 days.
• New monitors start from a baseline. Certificate Transparency and DNS record the existing state silently on first run, so you won't hear about what was already there.

Still convinced something was missed?

If a real event clearly went unnotified, open a ticket with the Open a ticket button below and include:

• the monitor name,
• roughly when it happened, and
• which channel you expected it on.

We'll check the delivery log with you and get to the bottom of it.
