Heroku 503 error when adding android platform


right now a friend and i are trying to add an android platform and when it comes to execute:

ionic cordova resources android --force

Crashes showing the following:

HTTP Error 503: POST https://res.ionic.io/api/v1/upload

It seems to be failing alternatively and it happens to both of us.

Thank you in advance!

I also have the same problem. Hope it will be fixed soon
