Hi,
We’re going to be doing some maintenance on the API servers tomorrow morning as part of deploying a game update. The maintenance period is on 6/11/2013 between 8AM-12PM PDT.
Some of the APIs (particularly the events API) will be unavailable at times during the maintenance period.
After the maintenance is complete, there will be a new state returned by the events API, “inactive”, that will be documented further tomorrow.
Apologies for any inconvenience.
