Hit a strange route issue earlier transiting Level3 network to GTT - Packet
Loss & High Latency - caused some interruptions in critical traffic flow.

Between Level3 hop 4.68.63.158 and GTT 144.136.105.226 - had a 20ms latency
increase and packet loss. After about 1+ hours the route had shifted and
latency dropped back down. Does anyone have details on this by any chance?
