There is currently pocketless towards Telia network from Västberga (5.226.32.0/21 and 46.253.192.0/20) datacenter. We’ve notified upstream transits who are looking into it.
If necessary we’ll disconnect Cogent temporarily to re-route traffic until it has been fixed, we’ll keep monitoring for now.
Update: Traffic for Västberga has been re-routed away from Cogent during the duration of the packetloss.
