If it doesn’t turn out to be a Mikrotik bug/issue… It almost sounds to me like the PPP keepalives (which is Link Control Protocol, LCP) are being starved out by the actual data.
If this is a Chorus circuit, I’ll keep across it with the Quic crew 👍
From the linked video at about 2:05 when the pause starts the PPP interface is still showing as running (the R on the left), and there's a few kb/s of traffic which wouldn't be there if the router thought the PPP session had dropped.
LCP runs in both directions and can have different timeout and lost packet settings - maybe the BNG thinks the link is gone :) Anywho, Quic will be able to see that.
I can think of two things might be going on, I have had this before when you really push a connection only when torrenting I was on spark at the time, It was triggering the DDos protection they had.
It would just start up really get going then 1 min into it everything would stop All connections would drop nothing would work, It would come back online about 5 mins later. nothing was required.
Other thing is when it does happen is the ONT all showing the correct links and lights on.
Updated MTUs and updated ROS as well, and then tried doing the multiple Aspera downloads to saturate the line.
The values sat at 2-2.1gbps max which makes a lot more sense - however, I still end up with the same issue, down to 0bps, no packets. Anecdotally, it seems like it is lasting longer before the drop happens?

Increasing MTU (packet size) may have reduced the number of packets throughput, if there was a DDoS filter that was packet counting then it would take longer to kick in.
The really strange thing is the timeout. I can sit here, do nothing, and after 60-240seconds, then i see data running through pppoe/vlan/sfp+ interfaces. Sometimes that will happen immediately if I apply "dial on demand" on the pppoe interface.
Hitting apply for any setting will reset the interface, same as disable/enable.
