Patch day. Go get some cereal.
If you couldn't log into Pirates of the Burning Sea this morning, it was because they were implementing their latest patch.
On Tuesday morning, March 18th from 1:30a to 3:30a [edit: 7.30a] Pacific Time, Pirates of the Burning Sea game servers will be unavailable while we move Build 184.108.40.206 from Testbed to Live.
