Zendesk will perform emergency maintenance which will impact performance for some customers on Pod 19 using Support, Knowledge and Voice, during the time listed below.

Affected products: Support, Knowledge and Voice interfaces and APIs may be unreachable. All other products reliant on Support, Knowledge and Voice data may have a degraded experience.

Important: Impacted customers will be notified through the in-product messaging banner in Support. If neither the account owner nor any admin sees the banner overlayed at the top of the Support interface, your account will not be impacted.
Customers Affected: Zendesk customers on a single database cluster will experience a maximum service disruption of 3 minutes at some time within the maintenance window.

Expected behavior: The Support, Knowledge and Voice interfaces may briefly be unreachable, and your agents may experience server error screens, sluggish response times, issues bulk updating tickets, refreshing ticket views, and Voice dropped calls. Some API calls that retrieve data from these products may also fail. 

Other products and integrations that are reliant on the data from Support, Knowledge and Voice will also be degraded. 

Please note that backend processes such as email processing will continue to operate as normal.

What do customers have to do? No action is required.

Why we're doing this: The Zendesk Database team is updating Databases for increased reliability and performance.
