    Does the post relate to a maintenance report feedback to public flat house (e.g., a broken facility, an inconvenience, block number or street, requst fixing, etc.)?

The Twitter post "failed 70kg backed 60kg x3 safra energyone" relates to a maintenance report feedback for a broken weight machine in a public flat house. The post mentions the weight of the machine (70kg) and the amount of weight that was backed (60kg), as well as the location of the machine (Safra EnergyOne). This information suggests that the machine is not functioning properly and requires maintenance to fix the issue. Therefore, the answer is:
