title: Multi-location synthetic monitoring alert conditions

With multi-location Synthetic monitoring alert conditions, you can create a monitor to notify you when a specific number of locations are failing at the same time.

## Why this matters [#feature]

For [Synthetic monitoring](https://docs.newrelic.com/docs/synthetics/new-relic-synthetics/getting-started/introduction-new-relic-synthetics) that runs in multiple [locations](https://docs.newrelic.com/docs/synthetics/new-relic-synthetics/using-monitors/add-edit-monitors#setting-location), a single location will sometimes temporarily fail for a wide variety of reasons. In many cases, a single, short-lived failure does not indicate a problem that would require a notification.

With multi-location conditions, you can set the number of locations that must simultaneous fail in order to trigger an alert event and send you a notification. For example, if your monitor is running in six locations, you might set a condition requiring four locations to fail before you receive a notification.

> #### ⚠️ IMPORTANT
>
> Multi-location alerts do **not** affect alerts policies for a Synthetic monitor. For example, [muting a Multi-location alert](https://docs.newrelic.com/docs/alerts-applied-intelligence/new-relic-alerts/alert-notifications/muting-rules-suppress-notifications) will **not** mute a [Synthetic monitor's alerts.](https://docs.newrelic.com/docs/synthetics/synthetic-monitoring/using-monitors/alerts-synthetic-monitoring#alerts-existing-monitor)

| Conditions per account         | This feature has a limit of 1000 conditions per account, but some types of infrastructure alert conditions also count towards this limit. If you get a notification that you've exceeded your limit, contact your New Relic representative or [Support](https://support.newrelic.com/) for assistance.                                                                                                                                                                                  |
| Status between checks          | A failed location check will be considered failed until it performs a successful check, **up to a maximum of 24 hours**. The evaluation buffer for Multi-Location Synthetics conditions has a 24-hour TTL (time-to-live). For example: a location may fail and then immediately become available, but we'll consider it failed until a scheduled check is reported as successful. If no recovery signal is received within 24 hours, the failure is eventually dropped from the buffer. |

Here's a diagram that shows how a four-location condition will be triggered for non-simultaneous failures:

![Synthetics multi-location alert condition diagram](https://docs.newrelic.com/images/accounts_screenshot-full_synthetics-multi-location-alert-diagram.webp "synthetics-multi-location-alert-diagram.png")

This diagram shows an example of how a four-failed-locations setting will trigger an alert event for failures that occur one after the other. Note that failed location checks will be viewed as failed until they next have a successful check.

## Create condition from Alerts UI [#create]

Before creating a condition, read the [rules for multi-location conditions](#rules).

/\*  \*/

1.  From **one.newrelic.com**, select [**Alerts**](https://one.newrelic.com/alerts-ai), then [**Alert policies**](https://one.newrelic.com/alerts-ai/condition-builder/policy-list).

2.  Click on the policy in which you'd like to create the classic alert condition or create a new policy.

3.  Select **New alert condition**.

4.  Select **Build a classic alert**.

5.  Select **Synthetics** and **Multiple location failures**.

6.  Click **Next** to select monitors to target.

7.  Click **Next**. Fill out the fields on the **Set thresholds** step.

8.  Click **Save condition**.

> #### ⚠️ IMPORTANT

> You can't view or edit multi-location Synthetic monitoring alert conditions in the [Synthetics UI](https://docs.newrelic.com/docs/synthetics/new-relic-synthetics/pages/view-monitors-alert-information).

## Create condition with the API [#api]

Before creating a condition, read the [rules for multi-location conditions](#rules).

For example, multi-location condition REST API calls see the [REST API calls for alerts](https://docs.newrelic.com/docs/alerts-applied-intelligence/new-relic-alerts/advanced-alerts/rest-api-alerts/rest-api-calls-alerts/#multilocation-synthetics-conditions) documentation.

To use the alerts REST API to manage multi-location conditions, use the [REST API explorer](https://api.newrelic.com/docs/#/Deprecation%20Notice%20-%20Alerts%20Location%20Failure%20Conditions).
