For the past few days availability of level 2 VIIRS data (all VIIRS sensors, both Chl and SST) has been hit or miss. No data a few days ago, then we received data the day before yesterday and now, since yesterday a data gap again. We have many VIIRS subscriptions. All of them void of data since 11/10 or 11/11. A few example subscription numbers would be: 1676, 2124 and 3718. Also, not sure if you are fully operational yet given the shutdown issues and completely understand if you are just working to spin everything back up. On a good note: I don't know how the shutdown affected your division, but you all did a great job of keeping data flowing during that time period. Many thanks for that. Very much appreciated!

Re: Level 2 VIIRS Data Subscriptions
Hi Oceani,
It sounds consistent with a temporary slowdown in the OB.DAAC Level-2 processing pipeline rather than an issue with individual subscriptions. When ingestion is recovering from maintenance or a service interruption, the subscription feeds can appear empty even though the sensors are collecting data normally.
The missing days typically backfill once the processing queue stabilizes again.

For general background on how REST-based subscription and delivery endpoints operate on the client side, this reference covers the fundamentals: https://pingmynetwork.com/network/ccna-200-301/rest-api
Have a good day,
