The IP NOC began investigating the root cause with Tier III Technical Support. It was reported that the issue was causing packet loss for customers. Operations Engineering teams were engaged, and Field Services were dispatched to a site in Chicago, IL to assist with investigations. Troubleshooting identified a protocol issue, and Operations Engineering worked with Tier III Technical Support to perform adjustments on the links. It was confirmed that the errors cleared. The traffic load was also lowered on cards in Chicago to alleviate any further issues. Should any additional impact be experienced, please contact the Level 3 Technical Service Center.<br>
