Yeah but the cause for this really surprised me. I'm still investigating.

Could I have your addresses? I would like to avoid to type them.

Craig: Does this issue also manifests itself on your personal hashrate graph?

The Dash pool's hashrate has dropped by half that's why we are finding fewer blocks. I don't know what you are trying to suggest here.

All IPs should be fine now. The Monero daemon slowly became more and more unresponsive. Restarted and fixed. Feels like baby-sitting a sack of fleas. :D

I've begun banning china from all servers looks like the ban is too broad. Could I have your current IP to verify?

Maintenance has completed and all servers are up again.
