Re: NEXRAD Level II Maintenance Notification - Wednesday April 24th, 2019 (ROC)

Radar Operations Center Engineering will be performing routine maintenance activities to the ROC portion of the Level II Network.  The activity is a software & security upgrade (and reboot) required on core router support the ROC internet connectivity. 

 Start Time: 5:00 PM (Central time) Wednesday April 24th, 2019
 Duration: 5 Hours
 Event: ROC Software & Security Updates (core internet gateway router)
 
 The activity will take about 5 hour to complete and will effect Data flow of the "Alternate Level II Path" for up to 10 minutes somewhere during that window.  (RDS Path)
 
 The Primary Data Path via the TOC servers is not part of this activity.
 (No service interruption via primary path is anticipated.)

Please keep BOTH NL2 client connections up to avoid data flow interruption.

  This upgrade is not subject to the current NCEP Critical Weather Day notification.
