Blog is offline due to certificate problems

[Nat J. Bennett]

The blog is offline. If you go there you'll get either a certificate error or you'll be redirected to Ghost's offline page.

If you do some beep boops you'll see that the problem is that Ghost is putting the wrong certificate on the site. (See beep boops below.)

Ghost says to contact support but you may also be able to fix this by deleting and recreating the configuration for the custom domain in the Ghost admin console.

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and

It appears to be working now.

Ah, I see someone's moved it from Ghost to Jekyll.
