So that is how they lowered the traffic on the cards in Chicago.

All my tickets got closed w/o confirmation.   Good thing they turned down the tcp-disruption settings /  "perform adjustments on the links".  It is also very disconcerting that ICMP and IPSec seemed to do better during this capacity problem; perception is important w/ traffic engineering, but not so much with NOC mad-libs.

Simultaneous to the below update, another notice indicated that OSP completed splice work which fixed the problem.  So we're double-fixed now.

Multiple cards have been ordered, and will be installed on equipment in Chicago, IL in an effort to balance the traffic load through the site and alleviate the issue. Field Services are currently en route to the site with the cards, and are expected to arrive shortly.
