AppDynamics SaaS Maintenance and Communications

What kind of alerts and data behavior can I expect during SaaS maintenance?


AppDynamics makes new releases available every 6 weeks. Our goal is for all customers to be on the latest release, so they have access to the latest features and fixes.


Note: You must have a current contract for access to SaaS maintenance.

What do I need to know about build configuration?

AppDynamics will strive to upgrade your pre-production Controller before your production Controller.

For older Controller environments with mixed pre-production and production Controllers in the same environment, we are not always able to upgrade pre-production first.


When are the maintenance windows in my region?

The following table shows all maintenance windows, by region.


Pacific Time

Local Time




12 - 3am EST

Sunday through Thursday evenings



12 - 2am GMT

Monday through Friday



2 - 5am JST

Monday through Friday


The typical maintenance window is 2 hours. 


What downtime should I expect during maintenance?

There is typically no downtime of the Controller during upgrade maintenance. Logged-in user sessions will expire and force users to sign in again.


There is not typically a gap in metric data — however, customers may occasionally see up to a 2-minute gap when the old and new Controller instances are swapped out.


Where can I view the SaaS service status?

The SaaS Service Status displays data related to your upgrade schedule. You can find it at, by clicking the Service Status button in the top right corner of the page. See Where can I view the SaaS Service Status? for step-by-step instructions. 


Note: To see SaaS service status details, you need to be:

  1. Associated with a license 
  2. Logged in to 


How does AppDynamics alert customers of maintenance?

Customers can be notified in two ways:

  1. Email
  2. SaaS Status page

Customers register to opt-in or opt-out for email notifications at the individual level. Here are the instructions for how to opt-in.


What is AppDynamics’ Maintenance Alert Policy?

For planned maintenance, AppDynamics uses the following maintenance and upgrades policy to alert customers:

  • Notify customers a minimum of 48 hours in advance of regular maintenance. The only exception is for emergency maintenance.
  • Notify customers before and again after the maintenance. 

In the event of an issue during the maintenance window, the AppDynamics operations team will notify you within that timeframe, rather than waiting until the window closes.  


What if an upgrade can’t be completed? 

AppDynamics operations team will notify you if an upgrade needs to be re-scheduled, or if an upgrade is attempted and could not be completed.


What if I have questions or need help?

Is this page still current and accurate? It is dated November 2018. Are upgrades for major releases still done only on a yearly basis? Thank you.
