Messages sent by end-users via social messaging channels for these accounts will be preserved and buffered until the account is unlocked.</span></p><p><span style="color: #464646;"><strong>What do customers have to do? </strong>If customers have have enabled their own client-side </span><a href="https://developer.zendesk.com/documentation/classic-web-widget-sdks/web-widget/integrating-with-google/csp/"><span class="wysiwyg-underline">Content Security Policy</span></a><span style="color: #464646;"> than they must include *.zendesk.com on their allowlist to ensure that their integrations continue to initialize and function.</span></p><p><span style="color: #464646;"><strong>Why we're doing this:</strong> The Zendesk Messaging team is rehoming customers accounts to be located in the same data store as their Support accounts increased reliability, performance &amp; data locality.</span></p>
