URGENT: Production tenant deleted / missing from tenant list — returns 404 "Unknown host", need recovery

Summary: Our production tenant has disappeared and all our users are locked out. It is no longer in our tenant list in the dashboard, and the hostname now returns a 404. We need help recovering it urgently.

Tenant: referral-trail-production.eu.auth0.com (EU region)

Symptoms:

  • Every endpoint on the tenant returns HTTP 404 with body “Unknown host: referral-trail-production.eu.auth0.com, including https://referral-trail-production.eu.auth0.com/.well-known/openid-configuration.
  • The tenant is no longer listed in our Auth0 dashboard tenant switcher.
  • Our other tenant, referral-trail-develop.eu.auth0.com, is completely unaffected (returns HTTP 200 on the same endpoint).

Impact: Full production outage — no user can log into our application, and our backend Management API calls against this tenant are also failing.

What we’ve already checked:

  • DNS resolves correctly to Auth0’s edge, so the 404 is being returned by Auth0 itself.
  • The develop tenant working while production is gone tells us this is isolated to the one tenant.
  • Missing from the tenant list + serving a 404 suggests the tenant has been deleted (not merely suspended).

What we need help with:

  1. Can a deleted tenant be recovered, and is there a time window for this?
  2. What are the exact steps, and what does Auth0 need from us (verification, etc.) to restore it?
  3. Would the tenant’s users, connections, and application configuration be restored intact?
  4. Is there a way to confirm when and by which account it was deleted?

I can share our account/owner details privately with an Auth0 staff member — happy to DM. This is a live production outage affecting all our users, so any expedited guidance is hugely appreciated. Thank you.

HI @ruan1,

Welcome to the Auth0 Community!

I understand that you are requiring some pieces of information regarding your deleted tenant.

I have checked the tenant information from our side and unfortunately it seems that one of the eligible admins has actively deleted the tenant.

We are sorry to inform you about this, since our official Delete or Reset Tenants documentation precisely mentions that:

Deleting a tenant is an irreversible, destructive action and cannot be undone. Deleted tenants cannot be restored

I hope this clears up the situation and if you have any other question please let me know!
Best regards,
Remus

This is a serious matter. This issue is linked to a production system with more than 2,000 users, and the entire operation has been blocked. This system has been running smoothly for almost two years. Can we please communicate this urgently to resolve the issue, and conduct an audit to find out what happened and who was responsible?

@remus.ivan let me know steps or more direct communcaiton via email if needed to jsut seee what the options here is and how and why the tenent is gone

we have db witha ll linked user and auth0 is their a way to import all user and send reset passerd linked to them so that they can re setup their accounts, is thier no backups or rollbacks plans for such event? was the a intenital delete by ons of our admin user if so who and how?

Hi @ruan1,

I understand how frustrating this type of situation can be, and we are here to assist you in the best ways possible.

When it comes to restoring the previous settings of the deleted tenant, unfortunately this isn’t an available option at the moment, as described in the Tenant Settings - Delete tenant or subscription section as well.

Deleted tenants cannot be restored and the tenant name cannot be used again when creating new tenants.

We also do not have the permits of disclosing any piece of information regarding tenant changes directly here in the Community, so I have also send you a private DM, that includes further information on the matter.

Thank you for your understanding!
Best regards,
Remus
