Developer Instance cannot be opened due to some internal error

[anab66]

Hello,

Since yesterday 17th of September 2026, my developer instance doesn't open and this is the screenshot I'm getting :

Whe I go to "Manage my instances", my only instance "Zurich" is offline and when I try refreshing it, it stays offline

So I am stuck and cannot advance in my training.
I've enrolled for a new free PDI a few days ago to do a training on ServiceNow and it worked up to yesterday.
Thank you in advance for your help

ahoy @anab66,

it happens here and there to all of us, there's nothing to do but wait. It has been always brought back after some time.

If you need an instance immediately, you can enrol to some SN training (e.g. ServiceNow Administration Fundamentals) and there's a study lab instance available for a few days.

Or you might release the current and request a new instance but it would mean that you lose all your unsaved progress and data. As well as there might be waiting queue to grant a PDI... so it can also takes days to get a new one.

Hi @anab66 

Several community members have faced the same instance offline issue this week. 

I faced the same Instance offline issue post multiple refresh ( waited for 5-6 hours) on Monday with the following error:

“Bad Request
This combination of host and port requires TLS.”

Since I needed the instance urgently, I released the existing instance through the Developer Portal and requested a new one. I received the new instance within about 2 minutes.

If you’re okay with waiting, you can wait another 1–2 days or possibly longer   and keep refreshing/checking the Developer Portal. Hopefully, your instance will come back online.

Alternatively, if you don’t have any important work or data in your offline PDI, you can follow the same process I did and release the existing instance and request a new one.

Unfortunately, there doesn’t appear to be any support available for PDI.

I believe, you simply have to give it time and wait until it gets resolved.

Hi @anab66 

I’ve been using my PDI without any issues since this morning, but I’ve noticed several posts in the ServiceNow Community today reporting PDI failures or unavailability. Based on the responses and recent experience, this appears to be a known issue affecting multiple users.

A few points to consider:

1. There is currently no dedicated support available for PDI, so there isn’t much we can do from our side while the issue is ongoing.
2. If you can wait, I would recommend waiting a little longer. Some users have reported their PDI coming back online after a few hours, although there is no guaranteed timeframe. Based on recent reports, it may take anywhere from a few hours to 1–2 days.
3. You can release the current PDI and request a new one, but be aware that you will lose any data or configuration stored in the existing instance.

There have been around 3–4 community posts today about PDI failures or unavailability, so you’re not the only one experiencing this.

The issue might be related to ServiceNow's ongoing transition to a new release and the rebuilding/provisioning of PDIs, which could be contributing to instances being temporarily unavailable.

For now, patience is probably the best approach. If you have important data in the current PDI, I would avoid releasing it and give it some more time. If there is no important data and you need a working environment urgently, requesting a new PDI could be an option.

Hi @anab66, @leelamanjari,
There was a PDI outage late last week stemming from an infrastructure issue that was patched over the weekend.
The fix was rolled out in batches to affected PDIs, with most now back online and some still offline while the patch rollout continues. Please try logging back into your PDI in a few days.
