Black character selection screen

When I log into my world of Warcraft classic account. after I reach the character selection screen, all I see is a black screen. none of my characters are visible. I tried to scroll down and up, I made sure I am logged into the right account and on the right realm. I restarted the app and the computer. nothing worked. I even tried to create a new character, but a pop up says you cant create a new character. Please help me

Yeah, I made a post. Server is Down. Basically, we all couldn’t interact with anything for about 10 minutes and then it started logging everyone off. It’s apparently all US servers.

Only US West
