I contacted them. Here is their response.
Thanks for taking the time to write and for using our data.
No, it's not going away. Yesterday NOAA switches our western satellites production from GOES-17 to GOES-18 and we've been debugging some issues since then. We expect Animated GIFs to restart shortly.
Thanks again and please feel free to write if you ever notice anything amiss.
Regards,
Matt.
