  • Anyone managing a NextDNS config can whitelist the domain in question. I just did a basic site access check and the NextDNS blocklist is not currently blocking it but at least a couple of 3rd party blocklists are. NextDNS doesn't maintain 3rd party blocklists as they are independently managed. NextDNS does maintain their aggregate/recommended NextDNS Ads & Trackers blocklist though

      Greg B. Looks like the default blocklist is blocking perimeterx.net. I'm not sure which subdomains, the coloring scheme makes it look like *.perimeterx.net but it might be only a few (e.g. client.perimeterx.net)

      Omri Iluz so it's certain subdomain(s). I'd suggest following the troubleshooting article & possibly submitting an github issue


      Based on the tracking insights though, it seems unlikely that whatever blocklist maintainer is blocking it would allow a global exception since it does seem to technically collect, track, analyze data despite it's good use scenarios so situational whitelisting still be might the only feasible solution for those that use sites/services/apps from your particularly impacted company's subdomain(s)
