We are still investigating the root cause of why the underlying VM restarted. Once the VM came back up, we update Discourse to the latest stable release and the community site is now working as expected.
The emails were not sending due to the fact that we recently migrated mail providers and accidentally did not update the mail settings for Discourse. Thank you for your patience!
The underlying VM that is running our forums has gone down, we are investigating the root cause.
We have discovered an issue with our forums where background tasks are not running. This means that the forum is not able to send any email which also means that new users are not able to sign up.
We are investigating the root cause of this issue and hope to have the forums back up and running as soon as possible.
