Link to Moz Pro home 404s, and then I stumbled upon Moz's staging site...

I'm wary of giving more information as it's probably best that little to no one be able to access Moz staging for one reason or another. I should also mention that this was done very unintentionally on my part. That said, from the 404 from Moz Pro home, I tried to access "My QA", and that's when I realized that everything I did thereafter was within staging.moz.com (and posted a question similar to this one).

Does Moz permit access to their staging site, or did I stumble upon a mistake - or Moz-stake, if you will?

HOW DARE YOU ENTER OUR SECRET STAGING LAIR!

I'm just kidding, that definitely sounds like a major Moz-stake on our side. If you could shoot an email over to help@moz.com with any extra info about how you made it to the staging subdomain, we'll work to get that fixed up right away! As a side note, I really appreciate your discretion on this matter. Thanks!

It sure did. I'll email help@moz.com and provide more insight. Thanks!
