NEXRAD Level II Maintenance Notification - (Update)

The National Weather Service continues to work the latency issue.  In fact, the issue from Silver Spring to Norman causing the RDS latency appears to be fixed.  The other issue is TDS latency when the ROC is aggregate.  It is current under investigate.

To that end, the ROC has swapped the aggregate back to Norman in an attempt to trouble shooting the latency issue to Silver Spring.  This currently causes latency issues on the TDS (acting as the alternate, or back up feed.)  I believe users have made adjustments in the LDM configurations to mitigate this as an issue.  If this is still an issue with YOUR feed, please contact the ROC so we can assist.

THAT BEING SAID, it does not address client planned maintenance activities.  If the current NL2 troubleshooting impacts your feed options causing latency or outage, please contact me so we can address the problem and work with you.

Please let this serve as a reminder to keep pulling data from both the RDS & TDS paths to ensure the best data.  We've got half of the issue addressed and hope to have the remainder soon.

Radar Operations Center will be performing routine maintenance activities to the ROC portion of the Level II Network (ROC Facility) .  The activity effects the Internet II data path out of the RDS to the Level II users. 

PLEASE KEEP YOUR FACILITIES TDS CONNECTIONS UP FRIDAY NIGHT.
 
 Start Time: 6:00 PM (Central time) Friday May 11th, 2018
 Duration: 2 Hours
 Event: ROC Facility Router (RDS "I2" data path event).
 
 The activities will take place over a 2 hours and will effect Data flow of the "Alternate Level II Path"  for up to 30 minutes.  (RDS Path)
 
 The Primary Data Path via the TOC servers is not part of this activity.
 (No service interruption via primary path is anticipated.)

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