Hi there,
Why? We all can't tell, we are just random community members. I do assume you tried waking the instance through the Developer Site?
If so, same answer as always... PDIs are unsupported, there is no support for PDIs. Only thing you can do is:
1) Wait and hope
2) Request a new PDI
Don't get me wrong, just informing you, we all simply can't help you on this at all!
