At approximately 2:30 PM MST on Thursday February 19th 2020, Colorado 811 lost MPLS connectivity on our Level 3/Century Link managed circuit BBMD4611.  At 2:47 PM MST Systems Administrator created CenturyLink Ticket: # 18158445. Colorado 811 IT Team also began phone communications with Level 3/Century Link NOC at the same time.  Communications Administrator placed notices on social media directing users to Ticket Express and WTE for Emergency and Damage requests.  At 4:35 PM Colorado 811 engaged ATT Call Assurance to route calls to 800-922-1987 to a company cell phone with a pre-recorded message directing users to online services.  At 5:35 PM MST Century Link techs reported that they were on their way to the Network Operations Center to replace a faulty card.  At 6:00 PM a pop-up message was placed on our website to process Emergency Damage tickets on Ticket Express.  IT Team members continued to provide after-hours support alongside members of Operations and Member Relations.  At 7:00 PM MST Century Link/ Level 3 techs reported that they had successfully re-seated a network card at a Century Link/Level 3 facility.  At 8:00 PM MST services were fully restored, and after-hours Damage Prevention Agents resumed normal business duties.
