Splunk Observability Cloud domain change

This page announces the introduction of the new domain for Splunk Observability Cloud, discusses legacy and new domains, how it impacts new and existing customers, and helps customers prepare for the change.

We are introducing a new domain in March 2026: observability.splunkcloud.com. This domain provides an additional way to access Splunk Observability Cloud and its associated services.

The domain you choose will influence how you configure and use the platform, including:
  • data ingest configuration

  • Single Sign-On (SSO) setup

  • organization creation

  • user invitations

  • login and access workflows

Both the legacy (signalfx.com) and new domains will remain available until further notice, and we will continue to provide guidance as support for the new domain expands.

Product UI (SaaS URL)

New customers in March 2026 or later will access the Splunk Observability Cloud experience using the new domain observability.splunkcloud.com.

Existing customers will continue to access the Splunk Observability experience using the legacy domain signalfx.com.

This table shows you the syntax for both the legacy and new SaaS URLs for Splunk Observability Cloud.
Legacy URL New URL
https://app.realm.signalfx.com https://app.realm.observability.splunkcloud.com
https://your-org.realm.signalfx.com https://your-org.realm.observability.splunkcloud.com

API and Service URL endpoints

Both new and existing customers can access the API and service URL endpoints through the legacy or the new domains. These endpoints include ingestion, integrations, CDNs, Synthetic Runners, and streaming. See API and Service URL mappings for the legacy and new endpoint URLs.

Purpose of the new domain

The new domain highlights that Splunk Observability Cloud is a fully integrated and supported part of the Splunk Cloud Platform. It also simplifies navigation and provides a consistent experience across the broader Splunk product portfolio.

Domain availability

The new domain will be introduced to new and existing customers over the next three months. During this period, updates to documentation and platform components will reflect the new domain. These changes are informational only and will not affect any existing configurations.

Starting in March 2026, all new customers will access Splunk Observability Cloud exclusively through the new domain. Existing customers may continue using signalfx.com or choose to begin using observability.splunkcloud.com.

Domain rollout timeline

The observability.splunkcloud.com domain will be introduced between February and May 2026:
  • March 2026: Initial availability of the new domain observability.splunkcloud.com.

  • March - May 2026: Updates to default configurations and documentation across the data ingest ecosystem. All public product and developer documentation will be revised to reflect the new domain.

Required actions and recommendations

No immediate action is required. You can continue using Splunk Observability Cloud with your current SaaS configuration, URLs, and service endpoints (signalfx.com) without any changes.

Additional updates and required actions will be communicated separately as they become available.

Recommendations for future planning

To ensure uninterrupted access and data ingest, confirm that your organization can reach Splunk Observability Cloud using the new domain (observability.splunkcloud.com). Review your infrastructure for any network or security updates to identify any required changes to your network, security, or configuration settings.

Areas to review

Access issues typically stem from controls in the following areas:

  • Network controls: DNS (including custom/internal DNS), proxies, gateways, routing, firewall rules, and outbound (egress) allowlists

  • Security controls: endpoint protection, web/application firewalls, TLS/SSL inspection, and destination allowlists/deny lists

Key checks

End-user access (web application)

Verify that users can open and sign in to the Splunk Observability Cloud web UI using the new domain from all relevant environments (e.g., corporate network, VPN, VDI). Any saved or bookmarked URLs pointing to the old domain would need to be updated to the new domain.

API and tooling access (integrations and automation)

Confirm that systems used for integrations and automation can reach the new domain, including:
  • API calls used by scripts and services

  • CI/CD runners and deployment tooling

  • Third-party integrations that connect to Splunk Observability Cloud endpoints

Telemetry ingests (infrastructure and gateways)

Ensure that your instrumented environments can continue exporting telemetry data to the new domain, including:

  • Hosts, containers, Kubernetes clusters, and application instrumentation (agents/SDKs)

  • Gateway components (e.g., OpenTelemetry Collector running as a gateway)

Make sure the new destination is permitted through your network and security controls (proxies, firewalls, egress allowlists).
Note: These checks should be adapted to your specific infrastructure and system context. Additional steps may be required depending on your environment.

API and Service URLs changes

New endpoints are now available under the observability.splunkcloud.com domain. Existing endpoints will remain unchanged and fully supported.

The table below provides detailed mappings between the legacy and new URLs to support future planning and integration updates.
