Client broken or poblem with realm list

Since this morning im not able to conect in Lordareon. I was playing last night without troubles, but this morning when i tried, it said UNABLE TO CONECT.

I've tried everything!

I clean folder cache, then folder WTF, then chagend realm list, and still nothing. I deleted my old folder from WOW and paste another from my HD, did the changes and it keeps connecting and in the end. says unable to connect.

Im DL a new client, but I'd love to know if someone else is having the same trouble that im.

Is something about the client?

Is the server on?

Im running out of options, so if you could help me i really would aprecciatte lads.
