Latency issues

I've been experiencing some pretty bad latency issues on PoE for a while now, and just ran WinMTR to see if the issue could be resolved. It seems like there is an issue somewhere between hops "nash-bb1" and "chi-bb2".

Here are my results:

If there's something I can do to help resolve this issue please let me know, and otherwise thanks for your time.
