You may see messages sometimes in your cloud server operating system regarding the MAC address changing for the default gateway of our cloud i.e. 220.127.116.11 . This is perfectly normal behaviour as we balance traffic and routing across multiple physical machines with this IP address shared between them. As such messages in relation to this are normal system behaviour and not something that are indicative of any issue or problem in our cloud.
These messages can be suppressed in Linux/Unix systems by implementing the following setting or similar (depending on your exact operating system):
sysctl net.link.ether.inet.log_arp_ movements=0
