Me: do you have monitorin enabled for your cluster?
They: no

me: I recommend enabling it
they: naah, we're good

error: *occurs*
they: *try to guess at which hop which limits were or were not hit and/or which nw links could've dropped a packet with trial-and-error approach for days*

me: telemetry would give you an answer in under a minute....
They: ok cool. We're still good
