Zendesk will be performing scheduled maintenance on the WhatsApp Business API Clients hosted on our EU and US platforms. We have chosen to increase the maintenance window duration to spread the upgrades and reduce the load they generate on our infrastructure. Note that each WhatsApp Business API Client will be upgraded separately.
We will be rolling out this upgrade during these periods:

19:00 UTC / 11:00 PST |

Wednesday, November 10, 2021 |
US* |
23:00 UTC / 15:00 PST |
11:00 UTC / 03:00 PST |
* WhatsApp numbers hosted in the US region will only be affected from either maintenance window
Customers affected: All customers using a WhatsApp number
Affected products: WhatsApp messages within Sunshine Conversations and Support
Expected behavior: During this operation, customers may experience a brief period of WhatsApp message delay lasting less than 5 minutes. During this maintenance window, the rest of the Sunshine Conversations platform will remain unaffected and no service interruption will occur on any other parts of the platform.
When the upgrade of each API client is complete, WhatsApp message delivery will be fully restored, no messages will be lost, and no action will be required on your part.
Why we’re doing this: We will be upgrading all API clients from version 2.35.4, expiring December 21, 2021, to the current stable release recommended by WhatsApp.
