+1, which semi-large eyeball does Cogent NOT have capacity problems to?

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
