Is there a way to know when/if the whole website was down? And even better, the reason that it was down. I don't have access to the servers, only have access to Kentico admin with global admin privileges. Thanks!
Down as in the user trying to visit the site is getting a 503 Error?
If it goes down because of an error in Kentico, you would be able to check the event log, but if it is a server error you would need to check the server event logs.
There are a bunch of services online that will notify you when your site isn't responding like Uptimer Robot
