NEXRAD Level II Maintenance Notification - Wednesday October 19th, 2016 (Silver Spring)



    ROC engineering will be performing routine maintenance activities to the Silver Spring portion of the Level II Network.  The activity is a software & security upgrade required on all servers in the Silver Spring Level II cluster.
    
     Start Time: 10/19/2016 11:00am (Central Time)
     Duration: 1 Hour
     Event: ROC Software & Security Updates (NL2 software release 7.1)
    
     The activity will take about 1 hour to complete and will effect Data flow of the "Primary Level II Path Servers in Silver Spring" for up to 10 minutes.  (TDS Path).

To simplify and isolate the load process, the ROC will be moving the AGGREGATE function to Norman at 9:00 AM (Central) and moving it back to Silver Spring at approximately 3:30 PM (Central) the same afternoon.  This will cause a brief interruption in service each time from both locations when the AGGREGATE is moved but keeps the load procedure on the "backup node" vice the aggregating cluster.

 

     All system upgrades are subject to NCEP Critical Weather Day notification.

     If there is any emergency noted during this event, I can be reached at (405) 820-3646
     If there is an issue with the latency, my (8-5) desk number is (405) 573-3418

    And as always the ROC HOTLINE will assist as required or just track me down... (800)643-3363

    
     Thanks...
