Well it isn't down... it works, but added some more defensive checks to make sure it always works.

Android Private DNS works but stutters
2cd3855 
Android's DoT impl sends out test queries which may trip user-op that always
expects a url of a certain type, https://domain.tld/path1/path2, where path1
is blocklist-stamp; if not, path1="dns-query" while path2=blocklist-stamp.

By dealing leniently until such a time that proper blocklist-stamp validation
is implemented in dnsblockutil.js, do not error out when those are indeed
invalid.
