Abstract: We review the recent Cogent-Telia de-peering, including the countries impacted and various conjectures about the underlying business motivations. Once the peering session came back up, we observe Telia selecting many more routes to Cogent and Cogent selecting many fewer from Telia, implying this disagreement was at least partially resolved by adjusting peering ratios. Finally, we observe the new peering sessions that were established during the outage by both combatants and shifts in routing to other players even once service was restored.
