TQ has returned to service
A hotfix applied to Tranquility today inadvertently added a bug to the escrow system and a small number of players were able to exploit this bug for their own gain. Tranquility was taken down for a short time to fix this issue and deal with the exploiters. TQ has returned to service and will allow an increasing number of connections as the server goes through the start-up process. Please exersize some patience if you are unable to connect to the server for a short period of time.
CCP will continue to monitor TQ for other issues and irregularities. We sincerely apologize for the inconvenience.
