I am now seeing one of my services coming back online. For this service I have not replaced the CNAME. Anyone else seeing some service restoration as well?
There is one more problem I can think of (but yes you're right, it can't get worse than 'total outage'): Heroku might detect that the CNAME is missing and will deactivate some stuff from their automatic domain management / TLS certificate issuing.
Anybody know what the risks are for doing this? We have not one but 13 heroku domains running where we might do this.
What are the chances that their current work on the DNS issues might replace the underlying IP-addresses and hence we are making it harder on ourselves?
