Premium servers etc hypixel is not working, "Invalid session"

When I was opening the servers, it says "Invalid session", and I was so frightening to get banned or something else. So i opened the bugs website, yeah... Almost everyone is getting the same problem. The hypixel normally getting 60k-70k ppls online, now its dropped to arround 15k. Mojang, pls fix it asap, becuase its affecting too much people. Thanks!
