Zoom Phone users registered to the India (Hyderabad) Data Center will be automatically registered in an alternative Data Center (Mumbai) starting at 09th October 2026 04:30 AM PDT (5:00 PM IST on 09th October 2026). During the maintenance window, a brief disconnection may be experienced and notifications may be missed. If you get disconnected, the system will attempt to reconnect you automatically.

Traffic will continue to be routed through the Zoom's India (Hyderabad) Data Center once the maintenance is completed.
For customers that use hardware phones, refer to this link for the devices support the alternative datacenter process as described above: https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0061373#h_01GNZ783VT6YXHES8NSXBA5M9A
