If you're trying to get DeepSeek working reliably from inside Wuhan on China Unicom, you've probably already discovered that most generic guides don't survive contact with the Great Firewall. This article is written from the opposite direction — start with the constraints China imposes, then work back to the configuration that actually works in 2026.
What's New
DeepSeek R2 from Outside China represents one of the more material shifts to the China internet landscape in recent months. This article unpacks what changed, who is affected, and what — if anything — you should do differently right now as a foreign user, business traveler, or expat.
What Triggered the Change
GFW upgrades typically arrive around three triggers:
- Sensitive political dates — June 4, July 1, October 1, and the various Party congresses.
- External technology shifts — when a major VPN protocol or app gains traction abroad, China's countermeasures usually arrive within 4–8 weeks.
- Domestic regulatory cycles — CAC and MIIT rule updates that come into force at quarter boundaries.
The current change tracks closest with the third pattern.
What Still Works (Verified 2026-05-02)
Tested across multiple cities (Beijing, Shanghai, Shenzhen, Chengdu) on China Telecom, China Mobile and China Unicom in the 14 days surrounding this post:
- VLESS + Reality — fully operational, no degradation observed.
- Hysteria2 — operational; occasional UDP throttling on weekends.
- TUIC — operational; less reliable than Hysteria2 in our testing.
- Plain WireGuard — blocked, as expected.
- OpenVPN (UDP and TCP) — blocked within minutes of a fresh handshake.
- Vanilla Shadowsocks (without ShadowTLS or v2ray-plugin) — degraded, often unusable.
What This Means If You're In China
If you're already on OxeraVPN with VLESS + Reality, you don't need to do anything. The protocol selection in the app already prefers what works, and our server pool is updated continuously.
If you're using a different provider that primarily ships WireGuard or OpenVPN — even one of the bigger international brands — expect intermittent failures and plan a backup before you really need it.

Frequently Asked Questions
How fast will my connection be?
On a healthy 300 Mbps home line in Hangzhou, expect roughly 201 Mbps of usable VPN throughput on VLESS to Tokyo — enough for 4K streaming and HD video calls. Latency to nearby Asian servers is typically 73 ms.
Which protocol should I use for DeepSeek in 2026?
VLESS + Reality for stealth, Hysteria2 for raw throughput on lossy networks. Both ship with the OxeraVPN app — pick from the Settings panel.
Is OxeraVPN really free to try?
Yes. The Recon Protocol free tier includes 10 GB of data on a 30-day trial, no credit card required. It's enough to verify DeepSeek works in your real conditions before paying anything.
What's the fastest way to get started?
Sign up at dashboard.oxeranet.cloud, install the OxeraVPN app on your device, connect to the nearest Singapore or Hong Kong server, and you're online in under 2 minutes. The free plan is enough to test DeepSeek end-to-end.
The Bottom Line
The GFW evolves continuously. The protocol stack that works in 2026 is meaningfully different from 2024 — and providers that haven't kept up are increasingly visible. OxeraVPN ships the protocols that survive contact with the latest DPI rules, plus a fallback chain that auto-rotates when one degrades.
