We use (what was called) Web Safe now known as Child Safe for years.
Recently it no longer works. You can get to any type of website. It is clear this software layer style filtering you use for child safe has been upgraded with bugs galore, or the underlying network settings amended by an unrelated team without thinking - and by the number of posts it is broken for everyone, just many haven't realised it yet.
Please resolve it, escalate it to the top of your JIRA queue and get it fixed! It will clearly damage your reputation that you have absolutely zero child protections on your network. Just because I think its important I will probably alert several media agencies also,
(In addition the web safe admin page is broken as well now, as soon as you touch it , it complete drops all websites you added to the block list or any specific tick boxes like gambling and weapons)
