To restart your heroku dynos from the CLI, do the following:

CLI command is:

`heroku restart --app <app-name>`

This does not work for private spaces, for those you need to do:

`heroku ps:stop <dyno-type> --app <app-name>`

Where <dyno-type> is probably web, worker etc.

Once down, then you do:

`heroku restart --app <app-name>`

This has gotten about 10 apps online already for us so far - we are monitoring our fleet of 100 heroku apps and moving through the rest.

This is a pain in the butt.

12 hours in and sites are still down, https://status.heroku.com/incidents/2822

Still having issues, had a deploy (luckily just to staging) that seemed like it went through but old code still present in app. Can't restart dynos, cli commands sometimes work, sometimes don't.

Looks like we are getting production sites up and running again by restarting either via the CLI or the dashboard, worth a try if you are down.

Doesn't look like a cloudfront issue per se, though that is the error that comes up when trying to get to the Heroku dashbaord.

Now a wider isssue, status.salesforce.com is also down
