Spoiler, This is probably "SOP". A lot of data has a archive limit and is dumped if it is not accessed after X amount of time.
I am intentionally keeping this vague to not self-dox.
Source: I worked in gov for far too long and managed a massive publicly available data archive that also had a SLA that were based on international treaties and had to write up reports if the archive was offline for too long that went directly to the presidents desk.
I can't speak for this particular archive since I never worked on it.
Also, the Gov has been in talks with companies like Amazon for damn near a decade to move the archives into the "cloud" for "free" so Amazon (and I am sure google and microsoft) could sell access to the data if you were accessing it outside of their cloud. (build processing systems in their cloud, access is free, access it outside of the cloud and you have to pay for it). I thought it was corrupt as fuck and was pissed off about it. I quit that job a long time ago now.
