ACTION MAY BE REQUIRED: The EU4 Site Switch is happening on August 19 – Connexys Help

Since you are an admin of a Salesforce org on the EU4 instance, we want to inform you that we are performing a site switch on the instance on August 19, 2018.

The maintenance is scheduled on:

Sunday, August 19, 2018, 04:00 – 05:00 UTC

Performing this site switch will help to ensure that you continue to receive the same levels of performance you have come to expect from Salesforce.

After this site switch, your active instance location will be in our London data center and your ready instance location will be in our Frankfurt data center. Your instance name will not change.

During the maintenance, your instance will be available in read-only mode. This means that during this window, users can’t add, edit, or delete data on their org(s). For more information on what read-only access allows, see our Read-Only Mode Overview article.

What action do I need to take?

A site switch should be seamless to your users if you already follow our infrastructure best practices by not restricting access to Salesforce IP ranges, setting your DNS timeout value to 5 minutes (default setting), and not having hard-coded references in your Live Agent implementation.

Otherwise, please take the following actions before August 19:

•	Ensure your network settings include the complete and current list of Salesforce IP ranges to avoid any unintended service disruptions following the site switch.
•	If you control your DNS timeout values set, we recommend setting the value to five minutes. Otherwise, you may need to refresh your DNS cache and restart any integrations following the maintenance.
•	If you use Live Agent, remove any hard-coded references to API endpoint URLs in Live Agent or ensure these are manually updated after the site switch.

You can find more details on these actions and other FAQs in the Site Switching Overview article.

How can I get more information?

We will update customers via the Trust Site when the site switch starts and completes. We recommend subscribing to Trust Notifications to stay informed of this and other maintenance updates.

For any other questions, open a case with Support via the Help & Training portal. Be sure to include the topic #SiteSwitching in the subject line of the case form.
