Gemini Notebook Enterprise URLs change: go/ added to path, lm removed from hostname

Gemini Notebook Enterprise: Updated web addresses

The URL path for the Gemini Notebook Enterprise web app is changing in two ways. In both cases, existing links redirect automatically.

"go/" added: Starting immediately, go/ is being added to the URL path:

• For Gemini Notebook Enterprise,
  notebooklm.cloud.google.com/us/
  changes to
  notebooklm.cloud.google.com/go/us/.

• For Gemini Notebook within Gemini Enterprise,
  vertexaisearch.cloud.google.com/notebooklm/global/
  changes to
  vertexaisearch.cloud.google.com/notebooklm/go/global/.

The dates for this go/ path change are as follows:

Region Rollout date global and us Live eu Rolling out All other locations Starting November 9, 2026

"lm" removed: Starting November 16, 2026, lm is being removed from the hostname:

• For Gemini Notebook Enterprise authenticated with Google Identity,
  notebooklm.cloud.google.com
  changes to
  notebook.cloud.google.com.

• For Gemini Notebook Enterprise authenticated with Workforce Identity Federation,
  notebooklm.cloud.google
  changes to
  notebook.cloud.google.

Action is required: if your organization uses a firewall, proxy, or secure web gateway that allows access to Gemini Notebook by a specific URL path. If this applies to you, Google recommends that you add the following URLs to your allowlist:

1. Allowlist notebooklm.cloud.google.com/* and notebook.cloud.google.com/*

2. If you use Workforce Identity Federation, allowlist notebooklm.cloud.google/* and notebook.cloud.google/*

3. If you use Gemini Notebook within Gemini Enterprise, allowlist vertexaisearch.cloud.google.com/notebooklm/*.

Google recommends allowing entire domains (/*) so that future path changes don't require additional updates.

If you don't allow /*, you must allow both /REGION and /go/REGION, where REGION is your location value: global, us, eu, asia-northeast1, au, ca, de, europe-west2, in, kr, or sg. For example, notebooklm.cloud.google.com/us/ and notebooklm.cloud.google.com/go/us/

Temporary workaround: If your firewall blocks users before you update your allowlist, users themselves can access the original URLs by removing /go from the URL and adding version=legacy. For example: notebooklm.cloud.google.com/eu/?project=1234567&version=legacy. This fix will fail when Google sunsets the legacy version.
