The servers will come down for Update 18.8.16 on October 12.
- 13:00 GMT
- 9:00 AM EDT
- 6:00 AM PDT
The estimated downtime is 2 hours.
The servers are back up and the Halloween content is live, including the new instance.
You will find the new instance in Uturn Forest, but you'll first need to get the "buried" mission from a Draculeet in one of the capitol cities.
You have until November 7th to get all of the goodies!
