If the website you're trying to reach is due to a DNS issue, using OpenDNS for your DNS will resolve that. I remember years ago when there was a DNS-wide issue and I was still able to browse websites because I used OpenDNS.

So in addition to this Brave feature, the use of the free OpenDNS service might prove useful. Also, if you need parental content filtering, the OpenDNS service can do that.
