We’re investigating a node death which has resulted in markets and contracts becoming inoperable in game.
The issue is being worked on and we let you know here and on the EVE Status twitter account as more information becomes available.
Update 12:04: ESI is being disabled while we troubleshoot this issue.
Update 12:25: Tranquility Server is being shut down with a 30 minute timer as we roll back changes made to the server during today’s downtime. While not the cause, this rollback will revert the Griffin Navy fix and the Black Market Tax Haven updates from today’s patch notes until this issue is resolved.
Update 12:55: Tranquility is offline for rollback. This process may take 15 minutes before Tranquility is accessible again.
Update 13:06: Tranquility is now accepting connections.
And just yesterday @CCP_Tuxford was so proud of their efforts to outsource more and more aspects of the TQ cluster into external services on the EVE Domain services. Good start, good start.
You should leave it rolled back anyway. That change is total rubbish.
