Expected behavior: During the maintenance window, notified accounts attempting to use Messaging will find their accounts locked and unable to send outbound messages and instead will receive an HTTP 423 response. Messages sent by end-users via social messaging channels for these accounts will be preserved and buffered until the account is unlocked. What do customers have to do? If customers have have enabled their own client-side Content Security Policy than they must include *.zendesk.com on their allowlist to ensure that their integrations continue to initialize and function. We also suggest that customers use https://{subdomain}.zendsk.com/sc in place of api.smooch.io Why we're doing this: The Zendesk Messaging team is rehoming customers accounts to be located in the same data store as their Support accounts increased reliability, performance & data locality.
