My PDI is no working. My instance status is Refreshing past three days.

Hi @Aqib7 

1. There is no support available for PDI.
2. If you can wait, let's wait a bit longer.
3. You can release this instance and start a new one, but you will lose your previous data. To avoid losing update sets in the future, make sure to take regular backups of your PDI.

There have been 3-4 posts in the community today about PDI failures or unavailability. Based on the responses, you might need to wait 1-2 days and hopefully, the PDI will be back online.
