Our Norton family software is not blocking facebook. We have added the domains facebook.com, facebook.co.uk, facebook.uk.com, facebook.uk, en-gb.facebook.com, en-gb.facebook.co.uk, en-gb.facebook.uk.com, en-gb.facebook.uk to the block list, and the Norton logs show that the site was accessed but not blocked although the supervision settings are all switched on including social networking.
Any advice appreciated. All of our software is up to date
