Fredericton circuits stabilized overnight as local wind / cold conditions improved.  Circuit paths have been normalized.

Proper function of the Fredericton router hardware has been validated by vendor.  Paths exhibiting the majority of instability have been deactivated however the remaining circuits are also experiencing degradation, but to a lessener degree.  Extreme weather conditions a suspected to be a contributing factor and we are continuing to monitor.

CANARIE router in UNB, Fredericton has been experiencing degraded service due to multiple interfaces flapping. We are investigating root cause.
