massive slowdown due to dropped packets today

You cannot gauge packetloss with Ping tests. All network equipment is coded to treat ICMP as a LOW level response. So when a system detects pings from a single source, its going to discard them to prevent the routing engine from getting overwhelmed.

its also how they prevent 80% of the DoS and ADDoS attacks against those nodes.

Your tests are invalid and you need to run wireshark while you experience packet loss and run the packetloss detection script against the Pcap when you are finished.

It doesnt matter what app did the diags. Ping is not a good tool to use.

I wish Anet knew better :-)
