Both relays are showing low BWauth-measured bandwidth and are below the 2000 threshold for the Guard flag.
Recently BWauths were offline and the consensus algorithm reverted to self- measure. During that period the relays were above the 2000 threshold and were assigned Guard.
But even the self-measure was very low for a gigabit link in a tier-1 network (Quest).
Some more tuning work is probably needed to get performance up higher. Possibly network issues are at work. If a low-end consumer-grade router or firewall is in the picture, it could be the cause of the problem.
