This is a known issue right now. Some PDIs are randomly going offline for backend maintenance, and the PDI team hasn’t provided an ETA yet.

Your instance will be back up once the maintenance is completed, so if you have no urgent work, please wait for it to come online.

PDIs run on shared, temporary infrastructure, so they shouldn’t be treated as permanent. As a good practice, regularly push your scoped applications to a remote Git repository using Studio Source Control, so you can provision a new PDI and restore your code quickly if this happens again.

Hi @EmbelleL ,

Yes, based on recent ServiceNow Community discussions, this appears to be a wider PDI infrastructure issue affecting multiple developers.

You can refer to these Community discussions where other developers have reported similar PDI offline and 502 Bad Gateway issues:

1. PDI Offline – 502 Bad Gateway

2. PDI in Offline State – Resolving 502 Bad Gateway

3. ServiceNow Community – PDI Discussion

ServiceNow's PDI documentation also explains that instances may become unavailable during infrastructure maintenance.

Hopefully, your PDI will be restored soon without losing your existing work.

Hope this helps! If this resolves your issue, please mark the response as helpful and accept it as the solution.
