My incoming data to the node suddenly spiked from the usual 200 kbit/s to 11 Mbit/s. It has already tapered off, but I wonder what could have caused this.
It is IOTA traffic. It is one node which pushed that data to me. I think I was told that it is a swarm node, but I'm not certain about this. I have the IP and the DNS of the node which sent me that data, as well as the Slack contact for this node.
(I have the outgoing data limited to 1 Mbit/s in the INI file, that's the reason for the cutoff at the bottom, will change this this weekend)
I upgraded to 220.127.116.11 at around 8am so it was already running that version a couple of hours.
These are some graphs of the per-IP traffic from the machine that hosts the node
Outgoing traffic (The red block is DNS traffic)
