CoreSite Incident Notification


Description:  During a planned maintenance event to integrate new 
hardware into our MPLS core an extreme dip in Any2 traffic was observed. 
After about 4 hours running in a degraded state, an emergency case was 
opened with the hardware vendor. After working with the hardware vendor 
to rule out any possible hardware or software bugs, the network 
engineering team located the source of the traffic loss. It was an 
errant configuration applied by the custom automation written to build 
LSP's in our MPLS network. A formal IR will be provided for this event.
