Right now, in the morning Im enjoying 30-40 ms, around 4 PM it goes to 70-80, then come 8 PM its over 100 with spikes to 300 sometimes 1000. These cogent servers cannot handle the load and slow down. Why they are being routed through these poor servers has yet to be explained but when I can do a traceroute to an EU server and get better latency than one from a server literally a state over, it's a real aggravation.
