Password and username not valid for some time!?

[Sand.3082]

Ok hi all and just one question. Today when I wanted to log in my game using game launcher I could not and I got some error notification. I later heard from guildmates that its pretty normal and they too had this notification at some point, but what worries me is a fact that I could not during that time log in my account on guild wars 2 web page and every time I tried I was getting notification your password or username is not valid. I am sure my password and username were entered correctly and I was not using caps or anything since I tried several times. Can anyone tell me what did happen because my guildmates told me they never did have that error when trying to log in gw2 web page? Thank you in advance

Well if more people were having problems I would say login servers were down.
