FastTrack portal logon receives "Unknown Error"

[Troy Phillips]

When I attempt to logon to the Microsoft FastTrack Portal (https://fasttrack.microsoft.com/) with my partner organisational logon, I receive "The application has encountered an unknown error. Please try again at a later time.".

I have tried again for months and months and it doesn't seem to be a temporary issue ;) 

I assume that the portal is still working for others? Who do I contact for these sort of issues?

The only FastTrack URL that seems to work for me, is looking at my FastTrack profile (https://fasttrack.microsoft.com/v2/en-us/user/profile)
