Re: NEXRAD Level II Maintenance Notification - Wed. Sept 26th, 2018 (ROC) & Thurs Sept 27 (TOC)



BOTH Activities are complete.  (Norman AND Silver Spring loads.)

ALL connections appear good on the monitors, but if you experience connectivity issues due to the load please call.

NOTE: The ROC and NSB continue to investigate the latency issue between the Silver Spring and Norman location.   We will continue to investigate till it's resolved.
