Site Disappeared – HELP

Hi

I just downgraded to 4.7.1 as the update wasn’t working for me with my theme. My site had completely disappeared, I can’t even log in to Wp-admin. It’s been half hour and when I’ve downgraded before it’s never taken this long. I am hoping it’s just updating but my anxiety is going through the roof. Is this normal? If so how long can the maintenance phase take? Please help!
