Optimization for AdGuard DNS SERVFAIL issues #6029
Description
Subject: Optimization for AdGuard DNS SERVFAIL issues
I don't understand why AdGuard DNS servers are experiencing SERVFAIL errors. This happens both on my portable Wi-Fi device and when I use mobile data. This might be related to network restrictions in China, but I still want to use AdGuard DNS because it is excellent in terms of privacy. Therefore, I would like the AdGuard team to try to resolve these issues.
I previously made suggestions (issues #6004 and #5972) to mitigate these problems through DNS cache list policies and by distinguishing responses, but they were rejected. I currently cannot resolve these issues through other means, and I wonder if the official team could optimize and fix this.
Note: I prefer not to use domestic DNS servers, as they may have speed throttling, and their privacy standards may not match those of the official AdGuard DNS.
