Seems to be a salesforce issue: https://status.salesforce.com/generalmessages/10001540

We're seeing mixed results with our apps, both in the Common Runtime (EU) and Private Spaces. A few apps are up, most are down.

We are seeing similar results -- most of our apps are down hard; seeing some mixed traffic on select apps

For me the Heroku status page shows 'No known issues', while the Heroku Dashboard and all my Heroku hosted apps do not work.

+1 - has anyone had any luck getting in touch with heroku support?

we sent an email to support@heroku.com as suggested in the docs when unable to login: https://www.heroku.com/policy/support/#:~:text=If%20you%20ar... But nobody has come back to us yet

Salesforce Service Cloud is affected by the issue too, so if they are dogfooding their own customer service software there's a good chance their support team are locked out of accessing support cases too :/

nope, can't log in (SSO) to access the support area, sent an email to support@heroku.com

Same, can't log in and the support area needs a login... Not much fun to watch our pending queue grow and grow

Status page is unavailable now.

Dashboard and CLI are unusable. Apps seems to still work for the moment

You know things are bad when the status page is down as well...
