Since the hardware is not working anymore, I removed this server from the pool. In September. Last year. Today I can see frequent requests coming from about 15-20 different source IPs... Even the host name does not resolve anymore, so I assume I'm seeing traffic from very long running systems (or those with static configured IPs instead of host names). That's not a real problem and it does not consume any data volume. But what if I configured the server to have 100M bandwidth? To virtualization: My pool servers are virtualized with KVM on my very own KVM hosts. Monitoring says, the server is pretty accurate and provides stable time for the last 2-3 years. But I wouldn't setup a pool server on a leased virtual server from another provider. I see, that some hosters are doing weird things on limiting/blocking UDP traffic directed or originating from virtual servers... Regards, Max
