Aliyun authoritative DNS adds 100K/day cap on free tier — third cut in 18 months
TL;DR
Aliyun's authoritative DNS free tier adds a 100K query/day cap per domain from June 24. Third tightening since 2024 — recursive DNS also capped, new free signups restricted.
From June 24, 2026, Aliyun authoritative DNS (public NS) free tier adds a per-domain daily query cap: 100,000. Over the limit triggers dynamic throttling — including response latency and packet loss. Note: this is authoritative DNS (where your domain's NS points to Aliyun) — not the 223.5.5.5 public recursive resolver.
Third cut in a row. Aliyun's progressive tightening of DNS free users:
- September 2024: public recursive DNS free tier started rate-limiting by source IP — over 20 QPS or 2000 bps per IP triggers controls.
- Early 2026: free tier no longer accepts new bindings; only Wanwang-registered domains get free, others must buy paid plans.
- June 24, 2026: authoritative DNS adds daily query cap.
Is 100K enough? Aliyun says the vast majority of free users are well below — which is technically true; a typical personal domain at a few thousand queries/day is already a lot. But the issue isn't volume — it's the stability promise. Over-limit means «dynamic throttling, including packet loss» — unacceptable for production domains.
Personal recommendation: migrate to Tencent Cloud DNS. Tencent has launched paid plans but the free tier still has no published rate limits. Speed and stability for users inside China beat Cloudflare and fit China-facing domains better.
