With the resolver now legitimately escalating to TCP after repeated UDP timeouts to the same authoritative, each lame-server lookup takes ~50% longer to fail. The recursive-client backlog therefore peaks a little higher before the fetches-per-server auto-tune drops the quota below 200. Bump the upper bound for the burst-against-lame-server and recovery steps from 200 to 250 to absorb that extra latency. The lower bound and the final post-recovery target (clients <= 20) are unchanged. Assisted-by: Claude:claude-opus-4-7 |
