So this is driving me bats. The ping time from my firewall to the downstream hop (Sonic fiber) is 1-2ms .. except every 2 seconds it consistently jumps 100-200ms for about 0.3 seconds, before returning to the more usual 1-2ms. I have no idea why. I've tried different firewall hardware (both pfSense mind you) but the problem persists. The internal network is fine (and this ping-ing is happening from the firewall anyway).
So, just me? The command i'm using to see this is 'ping -i 0.1 <downstream ip address>'.
