More granularity shows symmetric "dips" for in- and outbound with a frequency of about 10-15 seconds:

CPU interrupts, softirq and softnet show matching dips:

I see the packets/s exceeding 400k now. But you're right, the daily peaks of the packets/s graph look unnaturally flattened the past few days, see attached graph. (Iran shutdowns marked in red.)

I don't know what those semi-periodic "dips" could be. Maybe garbage collection in the snowflake-server process?
