Planned maintenance of our US Data Center

General | December 6, 2017 | 1 min read

Dear Customers,

We had announced in September 2017 about the annual infrastructure maintenance of our US Data Centers in this blog. Because of unavoidable reasons, the activity was postponed and we promised to keep you informed on the future dates.

Planned Maintenance of our US Data Centers is scheduled from 17th December, 2017 to 31st December 2017.

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 center 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 and we’ll reach out to you immediately.

Update on last year’s maintenance activity can be read here.

If you have whitelisted our Zoho IP address, please include the following IP address also to the list
Thank you for your support. Zoho wishes you & your team Happy Holidays!
Peter Balaji
Director of Customer Service

    I know this is not the place for this but didn’t know where else to tell you.

    I recently started using Zoho mail, and what an incredibly pleasant experience! I previously thought gmail was amongst the best email interface but your site knocks the socks off of Google. You have no ads, clean interface will all the sophistication some of us want and works flawlessly.

    Review websites are clearly not doing Zoho justice as it took me a while to find you guys.

    Really appreciate your ad-free and cost-free services to the people…. with gratitude.

    This is a very bad time of year to perform this level of maintenance. The risk of lapses in service during part of the busiest time of year for the North American retail and entertainment economy is too great. I don’t know what your customer base in the northwestern hemisphere is, but even if it is 20-30% it warrants pushing maintenance until after the new year.

    I’m clear on what to expect, when to expect it, the steps I may need to take regarding IP addresses, and steps to take if I have any unexpected issues. Thank you, as ever, for being so proactive and thorough in your communication with us. You’re the best.

    Yes, please do some upgrades. The recent hiccups in such things as login screens (and others) are an annoyance (to put it politely)
