No they weren't, all were full, heavy, or very heavy.
If you wanting to play on the EU servers, I don't know about those.
omg.. forget I tried to help you. Good luck.
Look here:

Sort it by type and timezone. I know for a fact that all the "light" west coast servers are new. Probably same for "light" east coast servers.
Some new west coast servers:
Warriors of the Shadow (pvp)
Shadowtown (pvp)
The Maw (pvp)
Darth Xedrix (pve)
Drooga's Pleasure Barge (pve)
Empress Teta (pve)
Fa'athra (pve)
Perlemian Trade Route (pve)
Zakkeg Beast (pve)
Probably not the full list, but ones I noticed. There is also a new rp-pve server, not sure which one it is though
How do you know they haven't already done this? (Up the capacity). Also, its instanced. So for example there is Korriban(1) Korriban(2) etc. You are probably in a dead instance, or you are in a part where there are not a lot of players yet.
