Update: New App URL (DNS) Names

Overview

As part of the Flosum Backup & Archive 4.5.0 (Winter ’26) release, we are updating the DNS names used by our applications. These updates improve consistency, align terminology with the new Global Settings experience, and remove legacy naming patterns.

This article details what is changing, why, and what to expect during DNS propagation.

What’s Changing

We are updating two key parts of the URL structure:

1. Replacing user-pool with global to enable the transition from User Pool to Global Settings.

2. Replacing backup-us-v3 with backup-us to simplify the US URL and align with the naming convention of other regions.

No action is required from customers. All updates occur automatically. But if you have bookmarked the backup-us-v3.flosum.app URL, you will want to update your bookmark.

Important Notes on DNS Propagation

When the new URLs go live:

• Most customers will see the updated DNS within 5–10 minutes.

• In rare cases, full DNS propagation may take 24–48 hours.

• This delay is normal and expected.

• During this window, applications remain accessible via fallback URLs.

Fallback URLs

To ensure uninterrupted access, each region will have a fallback URL using the -fallback suffix.

Example format:

• Global Settings: global-<region>-fallback.flosum.app

• Backup & Archive: backup-<region>-fallback.flosum.app

These act as temporary alternative entries only if DNS propagation takes longer than expected.

Global Settings URLs

User Pool is being replaced with Global Settings. See the table below for the Global Settings URL for your region.

Region	User Pool	Global Settings	Fallback URL
United States	user-pool-us.flosum.app	global-us.flosum.app	global-us-fallback.flosum.app
Germany	user-pool-de.flosum.app	global-de.flosum.app	global-de-fallback.flosum.app
Japan	user-pool-jp.flosum.app	global-jp.flosum.app	global-jp-fallback.flosum.app
Australia	NA	global-au.flosum.app	global-au-fallback.flosum.app

Backup URLs

For the US region, the Backup & Archive URL is changing. See the table below for the updated URL.

Region	Old URL	New URL	Fallback URL
United States	backup-us-v3.flosum.app	backup-us.flosum.app	backup-us-fallback.flosum.app
Germany	backup-de.flosum.app	No Change	backup-de-fallback.flosum.app
Japan	backup-jp.flosum.app	No Change	backup-jp-fallback.flosum.app
Australia	NA	backup-au.flosum.app	backup-au-fallback.flosum.app

In summary

Changes:

1. The User Pool Application is being replaced by Global Settings for Tenant and User management. This is resulting in a new URL for all regions https://global-<region>.flosum.app

2. The US region Backup & Archive URL is being replaced with https://backup-us.flosum.app
