We had that in a previous release afaik.

Sounds like an emergency ticket will be a great value in a situation like this.

Hi Patrick, 

Are the domains showing in the Domains grid as “Failed to load”? In this situation, you would want to review the domains to see if there are any missing or broken files. If nothing obvious stands out, we’ll need to get config-only copies for local testing. 

I’ll send you a ticket so we can get config-only copies prepared. 

That is correct, I was getting the failed to load on the domains grid. I did end up getting it back up and running.
1. Made a copy of the service folder to a temp directory
2. Uninstalled build 8755
3. Fully removed the service folder 
4. Restored the service folder from the previous day's backup
5. Installed build 8747

The domains are now loading again and look to be working fine. Will update the ticket as well so can take a look at what happened to the service config's.
