Final Update – 18/11/2021 08:48:00 AM: A recent Border Gateway Protocol (BGP) configuration change inadvertently caused an unexpectedly high influx of networking traffic to a subset of Azure infrastructure, causing congestion that led to delays for users accessing Microsoft 365 services. Microsoft corrected the identified network configuration issue to restore traffic flow to healthy levels.
