As a part of our annual infrastructure maintenance, we are upgrading our US data center infrastructure from Dec 23rd to Dec 30th, 2016. While we carry out this upgrade, we would like to inform that Mobile Device Manager Plus - Cloud edition, as well as other Zoho services, will be fully operational.
We do not expect any major interruptions and you should be able to use all our services during this upgrade. We will update this forum post once the data center maintenance is complete. In case you experience any problems, please feel free to talk to us here, or email us on email@example.com.
