Hi Maplers, We are aware that players have recently been experiencing issues with server instability and lag. We have identified several different areas of improvement, but unfortunately due to the complexity of these areas, we don't believe a server maintenance will be able to address these issues and mitigate the lag. As a result, we are planning to implement several improvements in next week's v206 game update maintenance. These changes include key improvements to our logging systems and underlying code to help make communication between the client and our servers more efficient. We apologize for the inconvenience while we investigate these issues, and we hope that these changes next week will help reduce the recent lag issues players have been experiencing. -The MapleStory Team View on the Official Site
