As of maybe a week ago, Safeguard is no longer preventing me from turning off safe search mode in my browser (see attachment for an example of me searching via google.com).
The normal website blocking of categories do still seem to be working correctly.
My primary/secondary DNS servers are pointing to the right SafeGuard addresses: 213.120.234.42, 213.120.234.38 (see DNS attachment).
This happened around about this time last year too around about the time my Broadband IP address changed, which seemed to be somehow related, and was eventually resolved but I was never sure how or by who.
My investigations last time led me to understand that this is something that PlusNet need to get BT to fix since the SafeGuard DNS service is owned by them.
When I request for example "google.com" via DNS, when it is working correctly it should actually return the IP address of something like "forcesafesearch.google.com" (or whatever it currently is) rather than that of the normal "google.com". My understanding is that this is accomplished by BT's DNS server knowing that when requests come via my routers IP address it should return the alternative IP address instead of the regular one.

Thanks for your help.
