Expected Behaviour:
[I should still be seeing a large number of blocked domains >= the number when I first installed Pi Hole]
Actual Behaviour:
[Fresh install of Pi Hole on a Raspberry Pi (original version, Raspbian GNU/Linux 8 (jessie), everything went perfectly and the web interface showed around 126k domains being blocked.
