We have shuffled around some servers in light of various locations being decommissioned. New York has been replaced by our recent Washington, DC location. Seattle has also been decommissioned, however it has been replaced by another server in Seattle. Finally, Atlanta has been decommissioned; we recommend either Virginia or Washington, DC for east coast players.
Additionally, we are aware of downtime with the Argentina server, and have contacted the admins.
Update 12/13: We are happy to report we have re-opened the Chicago servers under a new provider.
Update 1/4: We have deactivated the Argentina location. There is currently no timeframe on if or when the location will return.
