You are absolutely right.👍

In addition to running the HIVE witness node on the VPS, I also run a local node on a Linux host at home. In order to avoid sudden power outages at home, I configured a UPS for the host at home. At the beginning, the host at home was very stable. But after three or two years, the host had power outages from time to time, which often caused my local node to crash. After careful investigation and analysis, I found that the culprit was the UPS. After I unplugged the UPS, the local node has been running stably.😅
