On April 20.
Daybreak Games Company announced today that most of their titles will undergo extended maintenance on April 20. The maintenance is set to begin at midnight pacific and is expected to run for a full 24 hours. According to Twitter, all services will be shut down as Daybreak migrates their backend servers.
[ALERT] On 4/20 at 12 AM PDT we will be starting a 24 hour maintenance period on some of our internal systems. We have a large migration of our backend which will impact all game services. During this timeframe all servers will be shut down until the work is concluded.

So far the maintenance has been announced for Everquest II, Planetside 2, H1Z1, and Z1 Battle Royale, and nothing has been announced for DC Universe Online or Everquest as of this publishing. Daybreak’s servers went down for unplanned extended maintenance last week, and this migration may or may not be related to that incident.
