I had this Rasperry Pi-hole running OK for about two weeks and I was watching the web interface every day, it seemed to run fine. It does block most ads.
At some point I was no longer able to log in remotely (VNC or SSH) and when I hooked it up to TV, there was no signal. I suspect it had crashed. The only way to recover was to reboot it.
Now it seems to work again, but the graph looks different, and there is a device with activity every hour. Most hits seem to be from a tivo domain, look at the token below and at this screenshot
What is happening here? the Pi seems to block fewer domains, but I still don’t see ads. You can see the gap where the Pi has crashed, and before that and after that there is that strange periodic activity every hour.
EDIT: forgot to mention, but tivoservice.com generates a lot of hits for some reason.
