I noticed that and started adding all the statistical sites etc. that if aren’t added then sites start to malfunction (especially google sites… thanks google for the bloat).
Another issue though… I’m noticing that even though i whitelist google.com (or *.google.com), that the filters still think that google.com is a VPN/proxy avoidance and blocks it anyways, even if whitelisted. I would think that the whitelist would get the final say, but instead the final word comes from OpenDNS. This needs to be reversed.
