what happened to entrecard

Last night I was trying to log on to the entrecard to do dropping, When I did it was very slow so I stop and thinking maybe I can do it today. But now I tried to log on many times hoping I can drop my card but I can’t log on. I don’t know why. Am I the only one who experiences like this now. I am worried if I can’t drop because I have two blogs. I tried to open their site every now and then but still can’t, what happened to them why this like this now. This is the first time that I had this kind of problem. I can drop my card to other site but I stopped it might not counted and I don’t want to waste my time.
