It has now been confirmed that we are unable to revert the global chat system. We understand that this affects a large percentage of our players, and for several days great efforts have been put forth to restore the global chat system to its original state.
The investigation is still ongoing, and additional measures are being put in place. Once this is complete, the global chat system is going to be backed up every 20 minutes.
We understand that this affects a large number of our players, and we apologize to those who were affected. Please note that there will be compensation for this issue. As previously stated, additional information will be posted about the global chat status as soon as it comes in. Although a revert is not possible, new information is expected to arrive in the future.
The Global Chat Server will remain down for maintenance for the near future. We will post updates on this issue as more information becomes available. We appreciate your patience as we work to resolve this issue.
We are brining the Global Chat back up within the hour.
Global Chat should be fixed as of this morning.
You will also get a global handle change with this morning's maintenance AFTER all the servers are up. To use this change just use the command /changehandle <user name> - WARNING: You only get one chance to change this name - check your spelling!!! GMs will NOT grant you another one if you make a mistake.
*edited to say that all servers have to be up before they can grant the global chat handle change - hang in there!*
The global chat server will remain down while an issue is being investigated.
We are also receiving reports that some have lost rename token - we're looking into this.
Global Chat has now been restored to its pre-publish status. Any changes that have been made since today's server maintenance have not been saved. Additional information on the global handle rename system will arrive as soon as it is available.
Global handle re-names are now available on the Training Room! Please, make sure you go check it out.
For those who have used their original global re-name option: this global re-name token gives you the ability to change your global handle *one additional time*
If you have never used your original re-name option: remember that these re-name options do not stack. This means you still have one chance to select a new global handle.
This will reach the live servers on a later date - once it is good and ready. Enjoy!
Global re-name tokens are now on the live servers 
Yippie!
We are aware that global chat problems are still occurring, and we consider this problem to be high priority. Currently, the global chat system is being thoroughly checked. This process is taking some time to complete, and at this time we do not have any further updates. We'll be sure any updates along once they come in.
