Constant requests to api.github.com from Pi-Hole device

Hey folks, I also have have a similar problem, currently 927 queries in last 24 hours (~1 query every 2 minutes) from localhost to api.github.com.

Pi-hole version is v3.2 (Latest: v3.2)
AdminLTE version is v3.2 (Latest: v3.2)
FTL version is vDev-437af07 (Latest: v2.12)

This is running on a raspberry pi 2 with stock raspbian Stretch and only pi-hole installed manually. I'm not overly concerned, just curious why this is happening. Installed about a month ago and its been doing this since then.

EDIT: Since I started writing this it queried github another 5 times!
