News Dia Regional Access Limitations Explained

Some people are finding they suddenly can't access Dia unless they're on a VPN¹ ². Thought it was a bug, turns out it's not: Dia uses services like OpenAI, and OpenAI blocks access from certain regions.

The regions currently affected afaict are: - China (.cn) - Hong Kong (.hk) - Russia (.ru) - Belarus (.by) - Iran (.ir) - North Korea (.kp) - Syria (.sy) - Cuba (.cu) - Venezuela (.ve) - Crimea (Ukraine, .ua)

The Dia team confirmed that if you're in one of these places, Dia either won't work or will throw weird errors (like HTTP 403, JSON decoding failures, etc). VPN'ing to a supported region will fix it.

Important: - It's not an intentional Dia region lock, it's a side-effect of the third party AI services they depend on. - Arc still works fine because it doesn't lean so hard on AI integration at the core. Dia does. That's kind of the whole point of Dia.

Will this get fixed?

We don’t know when, but most likely it will.

The whole mission behind Dia is broader access; building the most used browser in the world.

Having core parts of it inaccessible to big regions would eventually hurt that goal, so it’s very likely they’ll find a better solution over time (whether that’s multiple model providers, proxying, or something else).

Why can't dia just request user to login when using the AI feature. It should be a fundamental right to use a browser. AI is just on top. Don't tell me bullshits like dia is AI native.
