Heroku API or GIT issues again?

All our Heroku apps are operating, but on some apps Heroku is rejecting 'git push':

! Heroku Git error, please try again shortly. ! See http://status.heroku.com for current Heroku platform status. ! If the problem persists, please contact http://support.heroku.com.

We can push to some apps, not to others.

The status.heroku.com page says all is well, but I'm wondering they failed to get everything cleaned up after the mess the past two days?

Anyone else having trouble with pushing a new build?
