Due to the size of the Micro Machines gaming community, occasional server fixes are required to optimise the game and ensure the best possible experience for our players. In order to carry out these improvements, the servers must be taken offline for a short period of time. Please keep an eye on the Micro Machines Facebook page and also Answers HQ for alerts and other information about upcoming server outages.
