Dash0 Backend

Can data be removed from Dash0 after it has been sent?

Dash0 supports infrequent deletion requests, for example, to comply with GDPR.

If you expect frequent or periodic deletion requests, transmit anonymized data to Dash0 (for example, hashed user IDs) instead.

Where are Dash0's backends hosted?

Dash0 is running various backends in several regions.

By default, backends for organizations in Europe are hosted in AWS Europe, and backends for organizations in the US are hosted in AWS US.

For more detailed information, please reach out to your Dash0 contact.

Network Access

Which IP addresses should I allowlist?

If your infrastructure uses firewalls, WAFs, or IP-based access controls, you may need to allowlist Dash0 IP addresses. Dash0 publishes machine-readable JSON files that list all relevant IP addresses per region:

• Ingress IPs — IP addresses used by Dash0's ingestion endpoints. Allowlist these if your systems send telemetry to Dash0.
• Egress NAT IPs — IP addresses used when Dash0 sends outbound traffic, for example notification webhooks. Allowlist these if your systems need to accept inbound connections from Dash0.
• Synthetic monitoring IPs — IP addresses used by Dash0's synthetic checks. Allowlist these so synthetic checks can reach your endpoints.

Quotas and Limits
