Dear Customers, 

It’s that time of the year again and we thought we should let you know in advance. As a part of our annual infrastructure maintenance, we will be upgrading our US data center infrastructure from September 2nd 2017 to September 10th 2017. We did a similar data center maintenance activity around the same time last year as well. 

During this upgrade process, all Zoho services will continue to be operational and we do not anticipate any major interruptions in using our services. 

We will update this blog once the data centre maintenance is complete. In the rare event that you do experience any issues with our services, please feel free to tweet us @zohocares or email us on support@zohocorp.com and we’ll reach out to you immediately.

If you have whitelisted our Zoho IP address, please include the following IP address also to the list
8.39.54.0/23
204.141.42.0/23
Update: Sep 2nd, 2017: Due to unavoidable reasons, the maintenance activity has been postponed. We will update the new dates soon.

    Dear Peter,
    I used Yoho’s mail service for my company for 2 years ago, these days I sent email to my clients but many of them can not receive my email, when they called me again, I checked it is done, but they received no email. I felt very disappointed about this matter. If this can not solve soon, I have to change my service into Gmail to use for my company.
    Thanks

  247. Maurizio Breschi

    I do not understand why you choose a working period instead of an holiday period like August.

    • RMO

      @MB because minimal disruption is planned. RIF.

    • Phil

      +100000 agreed

    • AVL

      In the US only 4 of those days are business days. 4 days are weekend days (2 Saturdays, 2 Sundays) and 1 day, Monday, is a National holiday. August would not be a holiday period for the US.

    • Elizabeth March

      Maybe they’re on holiday in August too 🙂
