I've had 6 successful purchases on Empire over the past 3 weeks; the site has been under massive attack - especially the mirror sites; however, if you use the direct link: empiremktxgjovhm.onion it's always up and if you have your 2FA enabled, then there's not a need to verify the mirror. Upon logging in you will see your home page with your personal phrase (hopefully you have both 2FA and your personal phrasee setup). Those who do not - I suggest immediately setting them up upon returning into the market through a mirror verification and don't be fooled by putting in your PIN on mirror sites. All official mirrors begin with "empire" and all deposit addresses begin with a "3".
