Green and Blue servers missing, but Red shows

[Laulena3]

Hi all,

I'm new to the game - is my 3rd day of play. I had logged out of green for about 20 min for lunch. When I went to log back in, green was missing as a server option, although Red was showing. Not sure if this is normal and there is a trick to get them to come back, or if maybe the whole servers are down?

Thanks!
