Lately, there have been bouts of server lag that affects many users, myself included. At random times, (most recently just now, at about 6:32 PM ET), the server will lag, players will "rubberband", and many will be kicked.
At this time I will simply assume this boils down to network issues with our provider at the time of this report. In the future, please also submit an MTR report during the issues. https://ecocitycraft.com/forum/threads/lag-latency-issues.189726/
