Nextdns returns wrong ip

Again I am having the issue, where webpages are loading really slow die to nextdns. 

Nextdns apparently sometimes returns a wrong ip, leading to a webpage having to wait until there is a timeout. This has nothing to do with blacklists. They return a blockage. This is nextdns returns incorrect ops that do not respond, meaning the Webbrowser has to wait for a timeout.

Could nextdns please have a look at this. Apparently some of your entries are incorrect and are not updated fast enough.. this is now happening again for more than 24 hours. 

This issue only appears to happen if EDNS anonymization is activated.
