That's exactly what I'm thinking of. And actually, that's where I meant to leave this comment. I must have had both open in two tabs for copy/pasting the URL and picked the wrong one.

Much less consequential tab-tastrophe than the time I dropped a table in production because I thought I was in my Dev tab. Backups saved my job that day. And I never kept two SQL servers up at once after that day. :-D
