I am analyzing BGP routing data from RouteViews and noticed unusual routing changes affecting networks in Ethiopia on 
November 10, 2026.

I would like to understand whether these changes indicate a real network disruption, a routing policy change, or a 
measurement artifact.

What BGP indicators would help distinguish these possibilities?
