[PAR] Update of Load Balancer IP Addresses

We've updated load balancer IP addresses for applications and websites hosted on Clever Cloud. The new IP addresses now in use are:


We are going to remove 4 IPs that you must stop to use between now and August 23rd, 2024:

After this date, your applications and websites will no longer be able to use these IP addresses.

We still recommend to use CNAME DNS records when it's possible. To ensure that there is no disruption to your applications and websites, please make sure that your apex domain names are updated to point to the new IP addresses. You can update your apex domain names by editing the DNS records for your domain.


There should be no downtime for your applications or websites as a result of this change. However, if you do not update your apex domain names before August 23rd, your applications and websites may be unavailable.

What you need to do:

Review your apex domain names and ensure that they are pointing to the new IP addresses. If you are unsure how to update your apex domain names, please contact your domain registrar or Clever Cloud support.

For more information:

Please refer to the Clever Cloud documentation for more information about load balancers and DNS records: You can take a look at the changelog entry about this change:
You can also contact Clever Cloud support if you have any questions.
