<p><strong><span style="color: #464646;">Expected behavior:</span></strong><span style="color: #464646;"> During the maintenance window, notified accounts attempting to use Messaging will find their accounts locked and unable to send outbound messages. Messages may silently fail or result in visible errors in the messaging interface. 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><strong><span style="color: #464646;">What do customers have to do? </span></strong><span style="color: #464646;">If customers 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" style="color: #1155cc;">Content Security Policy,</span></a><span style="color: #464646;"> they must include <strong>*.zendesk.com</strong> on their allowlist to ensure that their integrations continue to initialize and function.</span></p>
<p><strong><span style="color: #464646;">Why we're doing this:</span></strong><span style="color: #464646;"> The Zendesk Messaging team is rehoming customer accounts to be located in the same data store as their Support accounts for increased reliability, performance and data locality.</span></p>
