I need help waking up m PDI. I used it last night but today(Nov 4) I cannot wake it up.

Is there something going on behind the scenes today (Nov 4, 2026) preventing some PDIs from becoming active? It's been offline all day.

 

Need some assistance.

 

Thank you.

Hi @EmbelleL,
From an infrastructure perspective, recurring
502 Bad Gateway and PDI Offline errors on a PDI can occur because PDIs operate in a shared and temporary environment.

 

ServiceNow hosts a large number of free PDIs on shared infrastructure. If another instance on the same underlying node consumes excessive resources—for example, due to a runaway script or memory-related issue—it may affect the availability of the node or container. As a result, the Application Delivery Controller (snow_adc) may temporarily lose connectivity with your instance, which can lead to a 502 Bad Gateway and PDI offline error.

 

Because of this, it is important not to treat a PDI as permanent infrastructure. A good development practice is to keep your application code independent of the instance by regularly pushing your scoped applications to a remote Git repository using ServiceNow Studio Source Control.

 

With your code safely stored in source control, you can release an unstable or unavailable PDI, provision a new instance, and retrieve your application code quickly. This approach avoids spending unnecessary time troubleshooting infrastructure issues that may be related to the temporary PDI environment.

Hi @EmbelleL 

 

This is now a known issue now and randomly user's PDI is getting offline for maintenance work and the PDI team has not yet provided an ETA for its resolution.

 

Backend maintenance is currently in progress in your PDI, and your instance will be up and running once the maintenance is completed.Wait for the instance till it is up if you do not have any urgent work .

 

 

As mentioned in the Community Admin’s response in the : PDI offline  thread, the team is proactively coordinating with the PDI team to resolve the issue as soon as possible, given that direct support for PDI is not available.

If you have urgent work, in that case , you can leverage using  related Lab instance  Else Release your instance and request for new (Australia).
