Does anybody have any ideas about my constant cache hit ratio?
If it is of any help, here's my server section of unbound.conf for
inspection if anybody finds anything obvious.
It's a 512MB VM with 1 core.
# statistics-interval: 0
access-control: 10.8.0.0/24 allow
access-control: 127.0.0.1 allow
access-control: A.B.C.D allow
access-control: ::1 allow
# The following line will configure unbound to perform cryptographic
# DNSSEC validation using the root trust anchor.
