| 2018-10-03 06:00 | 2018-10-03 07:00 | Campus Cluster - Networking | Maintenance is being performed on the OmniPoP uplink on ur1carne, which is the upstream router for all ICCP based network traffic. Engineers will work to transition the link from old optical transport gear to new gear that will be optically protected with automatic failover. | All traffic that would normally take this OmniPoP link will reroute through other WAN links on ur1carne. Downtime of < 15 min is expected within the hour window while engineers swing the fiber jumpers from the old optical gear to the new optical gear. There should be no impact to DES or any ICCP customers. Please contact NetEng if you notice any unexpected outages. | help+neteng@ncsa.illinois.edu |
