As an admin of a Salesforce org on the EU11 instance, we would like to notify you of an upcoming instance refresh maintenance.
In order to prepare for your organization’s continued growth, Salesforce occasionally needs to perform an activity, called an instance refresh, where they upgrade the infrastructure supporting your instance in their data centers. This will enable Salesforce to continue to provide your organization with the same levels of performance.
Following this maintenance, your instance will move to another data center within the European Economic Area, and the name of your instance will change. Salesforce will inform you of your instance’s new name approximately six weeks prior to the scheduled maintenance window.
Do I need to take action?
We have reviewed the information provided by Salesforce and have come to the conclusion that you only need to take action if you reference the instance in for example custom buttons or if you retrieve data like jobs, campus events and contacts via the webservice as described in this article. If you have a career website via Connexys, we will carry out the necessary change so you don't have to take action on this. Make sure other parties, for example intranet, also perform the necessary change if applicable.
The endpoint you currently use to retrieve the data via the webservice, will probably refer to the instance EU11. Since this name will change, you need to change the endpoint.
Getting the correct end-point
It is possible to change "EU11" to the new instance name (which is not known yet) after the refresh has been completed. However, you can and probably should use the custom domain that applies to your org. See this article on setting up a domain if this is not yet set up for your org.
You can find the custom Salesforce domain in Salesforce Set-up under Domain Management. See this picture:
The custom domain looks like this in most cases: "connexys-<4 numbers>". The soap address will then look like this:
As an admin of a Salesforce org on the EU11 instance, we would like to notify you of an upcoming instancerefresh.
In order to prepare for your organization’s continued growth, we occasionally need to perform an activity called an instancerefresh, where we upgrade the infrastructure supporting your instance. For more details, watch this recording of the webinar, How to Prepare for Your InstanceRefresh. Following this maintenance, your instance will be served from new infrastructure within your region, and the name of your instance will change. We will inform you of your new instance name at least six weeks prior to the maintenance.
NOTE: Your new instance will be on the same release and system maintenance schedule as your current instance.
Enable My Domain and Remove Hard-Coded References: Remove any hard-coded references by updating them to the subdomain that you created with My Domain. If you have not already implemented My Domain, we highly recommend you do so prior to the migration. NOTE: Not all hard-coded references are automatically updated upon enabling My Domain. Review the Updating Hard-Coded References andGuidelines and Best Practices for Implementing My Domain articles for more information.
Whitelist All Salesforce IP Ranges: If your corporate network settings or email security filters restrict access to IP ranges or data centers, please ensure that you are including our current ranges.
Prepare to Refresh Integrations: If you are experiencing integration issues following the migration, be prepared to refresh your integrations.
Prepare to Refresh your DNS cache: If you continue to see a "Maintenance in Progress" alert following completion of the maintenance, you may need to refresh your DNS cache.
Subscribe to Trust Notifications: Stay informed with activities related your instance. To learn more about what Trust Notifications are and how to subscribe, review the Trust Notification User Guide.
