Expect 30 minutes of downtime Friday morning.

The NA region shards will be coming down for a brief update at 8:00am PST, 1/6/12. The estimated downtime is  30 minutes.  Here's the patch notes:

• Now that the Fae Yule event has officially ended, Fae Yule goods can be found on the World Event Merchants in Sanctum and Meridian!
• Any lingering Fae Yule quests should be removed from your quest journal.
• Players can now re-spec their Planar Attunements! Visit your calling trainer in Sanctum or Meridian to initiate a re-spec. The first one is free, but you'll have to pay 100 Platinum for additional later re-specs.
