I do not know if it makes any sense or answers your question. I contacted CIC on 19-03-2018 to request which Visa office was processing my application. On 27-03-2018 I received the following reply " Thank you for contacting Immigration, Refugees and Citizenship Canada (IRCC). We are pleased to confirm that the information you provided was transferred to the Case Processing Center in Ottawa. If you would like to contact the responsible office directly in the future, you may find the contact information for the Case Processing Centre inenquiry , Ontario, on our
website. We hope the information provided is helpful in assisting you with your enquiry."
My MED was on March 09, and since then I am also stuck on IP1, despite such reply from CIC.
So I believe that have been moved to VOs. I think VO in this case is the VO where my application is processed, even though I am a FSW-O applicant.
Please correct me if I am wron in that
