2026 Mainland China GFW Circumvention Anti-Blocking · Airport Selection · Self-Build · Automatic Failover

Source: two rounds of deep-research workflow (multi-source fan-out + adversarial verification, 2026-05-30).Highly time-sensitive— protocol blocking status, airport lists/prices expire on a weekly basis; but selection methodology, line principles, and configuration writing remain valid long-term. Marketing numbers have been rejected by adversarial verification, see the "Untrustworthy List" at the end of the article. For a quick reference of operating rules, see the corresponding entry in memory wiki-fanqiang-jichang-proxy(that is for Claude to work with; this page is the complete reference for users to review).

Core conclusion (one sentence)

In 2026, no single protocol/line can withstand blocking all day long; the stable approach is a hybrid architecture split by protocol, line, and scenario: on the protocol side Reality stealth + Hysteria2 speed boost as dual backup; on the line side buy IPLC/IEPL dedicated line airports for unattended egress; on the client side use mihomo's url-test automatic failover;buy two providers for mutual redundancy, pay monthly not annually.

1. Protocol Comparison (Anti-Blocking Layer)

Counterintuitive: when using IPLC/IEPL dedicated lines the protocol does not matter — the dedicated line physical link does not pass through the firewall; stability comes from the line, not protocol disguise. "Self-build must use Reality" and "buy a dedicated line airport" are two different worlds.

Speed: on China's international lines with severe packet loss, UDP/QUIC (Hysteria2) is faster than TCP-based protocols (Trojan/SS-over-TCP); TCP-over-TCP effective throughput can drop 60-80% at 15% packet loss. Daily Reality speed is already close to Hysteria2; the latter only feels more "snappy" when loading (0-RTT vs 3-RTT handshake).

2. Route A: Buy Off-the-Shelf Airports

Anti-blocking depends on line type, not the hyped protocol

⚠️ In 2026-04 a large number of airports had their domestic relays shut down and reverted to direct connections; "bought a dedicated line plan" ≠ "always on a dedicated line", you must monitor actual performance.

Objective judgment signals (to replace marketing talk)

Operating for ≥2-3 years + active TG group with prompt admin replies + complete ticket system + airport owner is physically outside the wall(DlerCloud owner was arrested in 2026-02, all nodes went down) + large user base. Operating duration is necessary but not sufficient(long-established TLY, DuangCloud also ran away). Quantification: single airport ~8% daily failure rate → buying two reduces it to 0.7%, three <0.05%.One main line + one cheap backup line.

Candidate list (⚠️ all from affiliate rebate sites, use only as a starting point, must check blacklist before buying)

• Main high-stability: WgetCloud (Amazon Global Accelerator + dual-route CN2, ¥59-99/month, compatible with standard Clash subscriptions), Nexitally Naixi (established 2017 dedicated line), Qingyunti (all IPLC, but locked to self-developed client)
• Daily cheap: Longmaoyun (all IPLC ¥15/month, but reported to be locked to the official client), Beixueyun (Trojan relay ¥9.9/month), Coffee Cloud/Youtu (relay ¥9.9-29/month starting)
• SSRDOG(established 2022, IPLC/IEPL, quarterly payment ¥67.5 starting, anytls protocol provides standard subscription) — this actual purchase adopted

⚠️ Client compatibility is the most hidden pitfall: After being reported, Qingyunti, Longmaoyun, TNTCloud, Yinheyun, Weiyituyun only provide self-developed clients, no standard Clash subscriptions, cannot be integrated into mihomo/ClashX workflows. Recommendation sites never mention this. Criterion: supports iOS Shadowrocket/Stash → must have a subscription link, usable with desktop mihomo.

Runaway blacklist (ground truth source, not marketing)

github.com/limbopro/Paolujichang + TG @limboprobot. Confirmed runaways:DlerCloud/Qiangdong (2026-02), UBBOLINK (2026-04),oixCloud is a rebrand/takeover of DlerCloud (use caution); older sockboom, Ziyoujing, TLY, DuangCloud, Kuifanyun (2025), etc. are dead. Must check before buying.

Finding the official site: recognize the bare domain

Airports change domains across multiple rounds; almost all entry points across the web embed affiliate codes (even GitHub "official address" repos give register?code=xxx). Recognize the brand's own root domain(ssrdog.com / wgetcloud.org), do not open affiliate aggregation pages like vipaff.cc / c.jichangs.com (routed through others' commissions + phishing risk). Fake sites are rampant (wgetcloud.net is an unrelated VPS site). Verify twice before paying.

Payment discipline

Never pay large annual fees to airports you have not actually tested(annual fees vanish if they run away). In 2026 many airports cut monthly payments/trials (SSRDOG, WgetCloud only offer quarterly payment as minimum). Pay monthly first if possible, gradually move to quarterly (¥60-135 is acceptable trial-and-error cost). "Price increase countdown" is a pressure-selling tactic, ignore it.

3. Route B: Self-Built VPS

Line quality and evening peak stability ranking

IPLC/IEPL(physical/logical isolation, packet loss <0.1%, almost no drop during evening peak) > CN2 GIA(China Telecom AS4809 bidirectional high priority, evening peak latency only +5-10ms,cost-performance sweet spot)> CN2 GT(return route may fall back to 163, quality degrades during evening peak) > Direct connection 163(evening peak latency doubles).Evening peak (22:00) shows the biggest gap. The higher the isolation level the more stable, derived from architecture not marketing. Hong Kong/Japan have the lowest latency to mainland China.

One-command multi-protocol deployment

reality-ezpz(github.com/aleskxyz/reality-ezpz): one docker-compose simultaneously deploys VLESS+Reality / Hysteria2 / TUIC / ShadowTLS(the latter three require the sing-box kernel, cannot be stacked on the same port as Reality).Only solves protocol deployment, does not solve datacenter selection + multi-node redundancy.

Unresolved (not fully investigated this round): which specific VPS providers (BandwagonHost/Vultr/DMIT/RackNerd/Oracle) have IPs not yet blocked in bulk in 2026 + monthly cost + frequency/cost of IP replacement when IPs are blocked. If you want to self-build you need to research this separately.

4. Configuration Layer: mihomo Multi-Node Automatic Failover

• Egress = system proxy, sandboxed Chrome/scraping inherits it, no hardcoded ports. Migrating egress = changing system proxy ownership (networksetup, instant rollback).
• url-test group: periodic (interval e.g. 180s, can adjust to 120s if response to dead nodes is slow) health checks select the lowest-latency node,tolerance(50ms) prevents flapping when latencies are close,url: generate_204. IP blocked = probe timeout = automatic switch.
• fallback group: when current node times out, switch to the first available node in list order; but during partial packet loss (degradation not full block) it will oscillate and switch back(no stickiness); for unattended use prioritize url-test+tolerance.
• To add a proxy-group in Clash Verge Rev you must use Script.js(global script merge);append-proxy-groups this version does not recognize it (it will be ignored as an invalid top-level key). After making changes you must reactivate the profile for it to take effect.
• mihomo API: Verge uses a Unix socket /tmp/verge/verge-mihomo.sock,curl --unix-socket … /proxies/<组> see now,/group/<组>/delay?url=… to trigger latency tests.
• Do not let two clients fight over the system proxy: only one of ClashX and Verge can have "Set as system proxy" enabled; when migrating turn off the old one first then turn on the new one, keep the old client as hot standby.
• anytls nodes require a browser restart to recognize the new egress: after switching the system proxy, already-running Chrome sticks to old connections; restart the sandboxed Chrome for a clean switch.

5. Multi-Device Implementation

"Dual-stack proxy" via soft router: LAN terminals disable public IPv6 (to prevent leaks), the soft router itself retains IPv6 to connect to VPS nodes, core uses sing-box/mihomo. Same origin as ClashX/mihomo workflow, covers Mac + phones + whole house.

6. ❌ List Rejected by Adversarial Verification (Untrustworthy, Do Not Use)

These come from airport recommendation sites/single blogs, and were rejected with a score of 0-3 during verification,do not use them for decision-making:

• "Reality 98% bypass rate / Hysteria2 dropped to 68% / speed limited to 1Mbps / Salamander obfuscation" — precise percentages are all fabricated (greatfirewallguide)
• "IPLC completely bypasses GFW, never gets blocked / a certain airport has been stable for 9 years" — marketing talk
• Precise numbers like "CN2 GIA non-peak national average 40ms" — from blogs of vendors that only sell CN2 servers, no methodology/sample/date; only directional conclusions (GIA barely changes during evening peak, direct connection doubles) are confirmed by multiple sources
• Only take the directional claims from these sources (Reality is strongest, QUIC risk rising, IPLC most stable), do not take specific numbers

Trustworthy: parts that can be corroborated by USENIX 2025 academic paper (gfw.report), XTLS official documentation, reality-ezpz repository, mihomo official wiki, limbopro blacklist (independently confirmed by non-commercial X observation accounts).

7. Timeliness Warning

All protocol blocking statuses, airport prices/status are a snapshot of the first half of 2026. GFW detection capabilities (especially in the QUIC/UDP direction) continue to upgrade; Hysteria2/TUIC risk only rises; airport runaways are high-frequency events (DlerCloud 2026-02, UBBOLINK 2026-04),before purchasing any airport name you must cross-check against the limbopro blacklist + TG intelligence channels for re-verification. expires: 2026-11-30, rerun deep-research for incremental updates upon expiration.
