The Message of the Day was just updated. A hotfix was deployed during downtime with the intention of optimizing some of the server code. It appears that the hotfix had the opposite effect and playability has suffered as a result.
The issue is being looked into and it may be necessary to remove the hotfix. If it is necessary to remove the hotfix, we hope to do so without taking the server down. If it is necessary to restart Tranquility, we will give advance warning.
Update: The server will be rebooted at 2045 GMT in an effort to resolve the problem.
