Stochastic Guard Flag symptom and the subsequent interruption of optimal contribution to the network.

Tracking issue with some relays in family randomly losing Guard in consensus, and experiencing other low bandwidth situations sporadically.

Not affected (always Guard once Guard):

Note about traffic graphs when not-Guard: the middle relays appear to be handling plenty of capacity; some delta between usage in Guard or not is based on this type difference. Consider mean consensus weight fraction along with guard / middle probabilities.

Will update once consensus history is reviewed in detail for the period in question...
