Hello,
We send periodic 10-15Mbps bursts of traffic to a business partner and it appears to transition from Cogent to Century Link in Atlanta. During the day performance is normal and latency appears acceptable on a trace route.

But after hours latency spikes and throughput drops to less than 1Mbps.

Century Link stated that Cogent is oversubscribing the link, and that they've requested Cogent resolve the problem, but that action has yet to be taken. I've tried reaching out to Cogent but as we're not a direct customer they wouldn't provide assistance.
Has anyone else seen similar issues?
Thanks,
Aidan
