I'm interested to know if you find a solution to this. I've upgraded to 26.1 today and am in a similar boat. I have dnsmasq on Opnsense forwarding queries for ts.net to 100.100.100.100, and since the upgrade all queries that should be forwarded as such return a SERVFAIL. On top of this if I query 100.100.100.100 directly from within my LAN I get the same result. Hosts elsewhere on the tailnet can resolve ts.net domains fine.
EDIT: So, I've been fiddling with this and tried turning off "Accept DNS" in the tailscale settings. This seemed to make MagicDNS work again, and would break it again if I turned the option back on, but after toggling it a few times it seems to have settled into working again even with the option turned on again!
