+# How to disable usage data or telemetry for (or how to "airgap") a customer instance
+
+## Types of usage data we collect
+
+There are two primary ways that we collect usage data from self-hosted Sourcegraph instances:
+
+1. [Pings](https://sourcegraph.com/docs/admin/pings#pings): anonymous and pre-aggregated data packets).
+2. [Event-level telemetry](https://sourcegraph.com/docs/dev/background-information/telemetry): still fully anonymous, but includes full user event/activity stream.
+
+## How to disable collection
+
+For recent versions of Sourcegraph, disabling either form of usage data collection requires a license key tag that permits it.
+
+1. First, the customer must receive a [license key that has the appropriate tag(s) that permit "air gapped" usage](https://handbook.sourcegraph.com/departments/technical-success/ce/process/license_keys/). Currently, the options that permit portions of this are "Allow air gapped", "Allow disable telemetry export", and any enterprise plans that explicitly permit "air gapped" usage.
+  * When this license key tag is applied to the customer instance, event-level telemetry exports (#2 in the [list above](#types-of-usage-data-we-collect)) will be automatically stopped.
+
+2. Second, the customer may actually "air gap" their instance at this point. If they do so (e.g., via networking rules that disallow connections to Sourcegraph.com and other Sourcegraph-managed URLs), then by default all forms of usage data collection will be stopped.
+  * Note that if the customer doesn't have a license key that permits this, their instance will shut down and not allow further usage. Without the appropriate "air gap" license key tags, licenses are continuously validated by pinging Sourcegraph.com.
+
+3. Alternatively, the customer may choose to leave their connection to Sourcegraph.com open, but disable pings manually. This is done by adding (or updating) the following in their [site configuration](https://sourcegraph.com/docs/admin/config/site_config#reference):
+
+```
+...
+"update.channel": "none"
+...
+```
+
+Once the appropriate license key tags are applied and pings are disabled (via site configuration or networking), the customer will effectively no longer send usage data to Sourcegraph.
