Scheduled Maintenance - April 1-8, 2025 | Pods 23 & 26 - Messaging & Sunshine Conversations

Zendesk will perform critical maintenance which will impact performance for notified customers on Pods 23 and 26 on April 1 - 8 2025, during the times listed below.

Affected products: Messaging & Sunshine Conversations

Important: Only customers who have been notified and have Messaging enabled will be impacted, based on the Pod maintenance dates and timings below

Customers Affected: Zendesk Messaging and Sunshine Conversations customers on Pods 23 and 26 who have been notified, will experience a brief service disruption of 20 minutes at some time within the 30 minute maintenance window.

Date	POD	Start Time	End Time
April 1, 2025	23, 26	14:30 UTC / 09:30 EST	15:00 UTC / 10:00 EST
April 3, 2025	23, 26	14:30 UTC / 09:30 EST	15:00 UTC / 10:00 EST
April 8, 2025	23, 26	14:30 UTC / 09:30 EST	15:00 UTC / 10:00 EST

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.

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 for increased reliability, performance & data locality.
