This was resolved.

There have been no updates from the NWS regarding this so there are no further updates from us. We will continue to monitor the situation and provide any updates as we receive them.

From the NWS:
Data dissemination problems have resumed. Radar data, obs and
products (including WWA) are seeing frequent and lengthy delays.
NCF support are investigating the issue.

We do not believe the NWS has resolved the issues despite what's been communicated.
* NEXRAD Level 3
* Watches
* Warnings
* Observations (Degraded - Backup implemented)

NEXRAD Level 2 remains functional which means that Super-Resolution data can still be generated and disseminated by us.

Satellite Broadcast Network (SBN) data delays have been observed as of an hour ago, 1806Z.
NEXRAD Level 3, Warnings and other SBN products are impacted.

We are using our FAA source for observational data so that continues to flow at this time (except for GREarth).
