I want to know why Sentry’s event ingestion IP addresses look US-registered when my organization uses the EU data storage location, and whether I can keep event data in the EU when allowlisting those IPs.

Event data for EU organizations is processed and stored in the EU, with event data hosted in Frankfurt. The ingestion IP addresses are shared global addresses, so WHOIS or IP geolocation lookups may show the US. That registration information does not determine where your event data is processed or stored.

For EU organizations, send events to the *.ingest.de.sentry.io host included in your project's DSN. You should not use sentry.io or app.getsentry.com for event ingestion.

For the current ingestion addresses, see the event ingestion IP ranges.

Keep in mind that not all Sentry product data is stored exclusively in the EU. Certain account, integration, and organization metadata may still be stored in the US, and this location is not configurable. See what types of data are stored where for more information.

If you're setting up an allowlist, use the current ranges in the IP ranges documentation or retrieve them through the IP ranges API.
