I keep getting disconnected

Hello everyone. Today, I was playing Ruby Sanctum, and I got disconnected while fighting the boss. I've been online on two different accounts, I got disconnected from both. I couldn't connect for an hour. When I try to connect, it shows "Connecting", and after some seconds, "Unable to connect. Please try again later."
I've tried on both of the accounts, tried redownloading, it doesn't work. I came back home half an hour ago, connected successfully, was in the queue. When I checked WoW, I got disconnected from both of the accounts, and I can not connect once again. Please, help. Deleted Chache folders, took a look into realmlist, everything's fine. My internet's been working fine. Please help, and thank you.
I got dc-ed twice more times. I come to 800 queue, and get disconnected. Guys, please help me!!!!!!!!
