Since this year I have massive trouble accessing anything hosted on AWS during the evening hours like these. My ISP is Deutsche Telekom AG (AS3320) and it looks like the only route to AWS (AS16509) leads through Cogent (AS174). MTR is showing more than 30% packet loss through Cogent to an AWS target. I know peering between DTAG and Cogent has been historically bad, but I never noticed issues until now. What happened? Do any BGP nerds know more? #BGP #Routing #Internet #Backbone #AskFedi
