Blizzard opened the Borean Tundra realm earlier this month for players who wanted a fresh start, and now they've done it again. Thundgot posted all the relevant information on the new PvE Saurfang server, which launched yesterday, over on the official European World of Warcraft boards:

We're opening a new English Normal/PvE realm, named Saurfang, in the Misery Battlegroup. This is a fresh realm, thus no migration will be allowed to the realms during the first 90 days. Also, the Ahn'Qiraj gates and Sunwell will be closed, and you can't create a Death Knight on the realm until you have another level 55 character there (or 90 days have passed).

Please note that the starting areas may be quite flooded in the beginning, and the population cap is intentionally set a bit lower than normal to not have them even more flooded. The cap will be raised over the coming days as the population spreads out more.
