It has seen many installs over the years but it's now a backup DNS server. Looking at the filesystem this one has been a PiHole since 2018, it has essentially ran 24/7 bar some reboots and me moving between places.
I don't write anything to the SD, it all goes to RAM at /dev/shm and the PiHole will simply have to redownload the lists the few times it goes down. It would download them anyway daily.
