Starting with the deployments planned for the week of March 16th, we'll be modifying our weekly maintenance windows. Please review the table below for information about the new times for your region.

Weekly maintenance windows as of March 16th

In order to more quickly and regularly bring new Atlassian product features and fixes to you, we currently update your instances in weekly maintenance windows at the times listed below.

At some point during your maintenance window your Atlassian Cloud site will be unavailable for 15-30 minutes.

Getting notified about upcoming upgrades and news

We use the Atlassian Cloud blog to announce upcoming upgrades and the completion of them. We try to publish information about upcoming upgrades a few days prior to the weekly maintenance so that you can prepare for them if needed.

If you'd like to get notified about future upgrades and news, please subscribe to our blog.

Communication on maintenance windows

  • Regular weekly maintenance windows: We will not send maintenance notifications unless we need to deviate from the weekly schedule.
  • Other types of maintenance: For other required maintenance such as urgent fixes, we will notify you at least 12 hours in advance by sending an email message to all technical contacts listed under your account at, or by adding a banner to your site with information about the maintenance.

Changing your maintenance window region

The region of your maintenance window is determined by the time zone selected during the Atlassian Cloud signup process.

To change the window for your site maintenance, file a support ticket letting us know your preferred region. One of Support engineers will be in touch with you to update it.

  1. Hi

    Thanks for the advice.

    I am checking the meaning of the separate tables "Weekly maintenance windows as of March 16th" (all 4 hours) and "Regular weekly maintenance windows" (these are of different duration depending on timezone).

    Am I correct in understanding that the first table is general updates to common apps/infrastructure and the second table is specific to Atlassian Cloud user instances?


    1. Both tables refer to Atlassian Cloud user instances, the first refers to what the expiry will be from the 16th of March onward, whereas the second refers to the current window.

  2. What day of the week are the times listed in the "Weekly maintenance windows as of March 16th"?

    1. Apologies, that content was missing, it's still Sunday/Mondays. I've updated the table now.

  3. This page is not clear to me.

    1. What is the difference between:
      1. "Weekly maintenance windows as of March 16th"
      2.  "Regular weekly maintenance windows"

    2. What day of the week is the "Weekly maintenance windows as of March 16th"? It doesn't say here on this page.

    3. What is the impact to users? Will Atlassian Cloud products be unavailable during the maintenance periods? Or if not will performance be affected? 


    1. Sorry for the confusion Hugh, the first table refers to the windows after March 16 whereas the second table refers to the windows prior to March 16th.

      Maintenance windows are still Sunday/Monday, I've updated the table.

      Atlassian Cloud Applications will be unavailable for a short part (about 15-30 minutes) during those upgrade windows. We can't tell you exactly when during that 4 hour window they will be down, but they shouldn't be unavailable for the entirety of the window.

  4. Re: AMER (America, including U.S.) and Timezones in AEST.

    I would suppose most AMER people would assume AEST == EST. Which it's not.

    Perhaps better to declare times in ET and PT. 

    1. Martin,  AEST is Australian Eastern Standard Time.

    2. Yep, I changed the table to make timezones much more clear. The maintenance windows are locked to UTC though, so when daylight savings hits for various regions the window timing will change in your local time.

  5. What kind of disruption in service on Cloud based instances can we expect for your 4 hour maintenance window.  

    1. At some point during the 4 hour maintenance window your Atlassian Cloud instance will be down and unavailable for 15-30 minutes.

  6. This page is not clear.

    1. Apologies for that, I've updated it to be a little more clear, let me know if anything doesn't make sense now.

  7. This page looks unclear for me too.

    There is no information of UTC in the table "Weekly maintenance windows prior to March 16th".

    So I cannot interpret it to my local timezone.

    When do you carry out the periodic maintenance before March 16th in UTC?

    FYI, I live in Japan and my local timezone is JST (UTC+9 hours).


    1. The maintenance window runs from 9pm - 11pm JST prior to March 16th. I've added UTC times to that table as well. (smile)
