Silences & Quiet Hours

Silences and quiet hours are how you stop notifications reaching you without changing what anyone else receives and without touching what Tracedown records. Probes keep running, results keep landing in history, success rates stay honest. Only your mail stops.

This separation is the point. Muting an alert should never cost you the data behind it.

Silences

A silence is per user and per resource. You create one with the bell icon, which appears on a workspace, a project, a service, a project card and a service row.

Silences are personal. Silencing a service mutes your notifications for it and nobody else's — there is no shared "mute" that quietly stops your colleagues being paged.

Silencing a parent

Silencing an ancestor covers everything beneath it. Silence a workspace and you stop notifications from every project and service inside it. The descendants then show their bell as locked, with the explanation:

Silenced via a parent resource — manage it there. An explicit grant on this resource would keep it independent.

There is one exception, and the second sentence of that message points at it.

Most-specific-grant-wins

The rule

A silence applies at or below your most specific grant. If you hold an explicit grant on a particular resource, a broader silence higher up does not mute it — your own setting for that resource wins.

So if you silence a workspace but hold an explicit grant on one service inside it, that service keeps notifying you. Its bell stays live rather than locked, because your grant on it is more specific than the workspace silence.

This is not a UI quirk. It is exactly the rule the notification dispatcher applies when it decides who receives an alert, and the interface is simply showing you the outcome in advance. Understanding that explains the behaviour: an explicit grant on a specific service is a deliberate statement that you care about that service in particular, and a broad sweep of the workspace it happens to live in should not silently override it. A grant you went out of your way to hold outranks a mute you applied to everything.

Since eligibility follows grants, the bell only renders for users who hold a grant on the resource. Someone with no grant receives no notifications for it and so has nothing to silence. See Users & Permissions.

Managing silences centrally

Bells are convenient in the moment and easy to forget about. Every mute you create with one is listed in one place: Account -> Silences, under Muted resources.

Each entry carries a scope badge — Service, Project, Workspace or Global — and can be removed from there. This is the page to check when a service you expected to hear from has gone quiet: a silence you set during a deployment three weeks ago is invisible from everywhere except here and the resource's own bell.

Quiet hours

Quiet hours are account-wide rather than per resource: a recurring window — daily, or on the weekdays you choose — during which no notifications are sent to you at all, in a timezone you choose.

Where a silence answers "which resources", quiet hours answer "when". They are the right tool for not being emailed while asleep, and the wrong tool for a noisy service — for that, silence the service.

Overnight windows are supported. A 22:00–07:00 window spans midnight and behaves as one continuous nine-hour period, not two fragments you have to configure separately.

Quiet hours reuse the same recurrence builder as maintenance windows, so the controls are the ones you already know from scheduling downtime. One difference is worth knowing if you set quiet hours through the API rather than the editor: a quiet-hours rule that omits its timezone evaluates in UTC, not in the organization's default timezone the way a maintenance window does. The editor always writes a timezone, so this only concerns rules created programmatically.

Quiet hours are not a silence entry

Quiet hours do not appear in the Muted resources list on the Silences page. That list shows bell-created mutes only. If you have quiet hours set and go looking for them among your silences, you will not find them — they are configured in their own section of your account, and their absence from the mute list is intended rather than a bug.

Choosing between the three

Maintenance window Silence Quiet hours
Scope Per service Per user, per resource Per user, account-wide
Probing Paused Continues Continues
Results recorded No Yes Yes
Affects Everyone Only you Only you
Driven by A schedule you set The resource The time of day

Read the table top to bottom and the decision usually makes itself:

  • Deploying, and the service will legitimately fail? Use a maintenance window. Probing stops, nothing is recorded, nobody is alerted. The cost is that the outage leaves no trace in your history — which is the intent for planned work, but means you cannot review it later.
  • Something is known-broken, being worked on, and you want the data but not the mail? Use a silence. History stays complete and your colleagues carry on receiving alerts.
  • You simply do not want email overnight? Use quiet hours.

The common mistake is reaching for a maintenance window to stop noise from a service that is genuinely failing. That does stop the noise, but it also stops the probing — so the record of the incident you are trying to fix has a hole in it exactly where you needed the evidence.

What silences do not cover

Silences and quiet hours apply to email. Webhook deliveries are bound to resources rather than resolved to individual people, so they are not affected by anyone's personal settings and will keep firing through your quiet hours.

If a webhook feeds a paging or chat integration you need to quieten, pause its binding instead — each webhook binding has its own enable/pause toggle. Note that this affects everyone, not just you. See Notifications.
