Claude Opus 4.6 (Thinking) completely unusable — persistent "high traffic" errors all afternoon, hundreds of retries with 0% success

[qin_yi]

I’ve been experiencing persistent capacity errors when using Claude Opus 4.6 (Thinking) in Antigravity IDE. The error message is:

“Our servers are experiencing high traffic right now, please try again in a minute.”

The attached screenshot shows just one example — the agent retried 5+ times before terminating with “Agent terminated due to error.” But in reality, I’ve been experiencing this issue the entire afternoon, retrying hundreds of times across multiple conversations with a 0% success rate. Claude Opus 4.6 (Thinking) has been completely unusable for the whole day, not just a single session.

I’m an Ultra subscriber paying for premium access, and getting zero successful completions over an entire afternoon is unacceptable. In the Asia-Pacific timezone (afternoon hours), the model is effectively non-existent.

Questions:

1. Is there a known capacity issue with Claude Opus 4.6 (Thinking) on Google Cloud?

2. Are there plans to improve availability for Ultra subscribers?

3. Is there any recommended workaround beyond switching to a less capable model?

Environment: Antigravity IDE, Ultra plan, Claude Opus 4.6 (Thinking), Asia-Pacific region

Thanks for any guidance.

same here can’t use any model at all!

[Marwane_Bouziane]

same here, I also can’t use any model at all!

All models (including Claude, Sonnet, Pro, and non-Pro) are currently not responding.

[Mark_Benner]

It seems to have been fixed.

Not at all, I am still facing this issue. also there is no result, it is using the quota dramatically high.
this is the good for google, don’t let the users use their product even a bit but charge high. At first i thought it might be a network issue, because sometime this same message comes when there is network issue, but then i tried web search as well as send some requests to Claude sonnet 4.6 in copilot, then i understand that this is not a network issue at all, it is actually a google’s problem.

me too . Antigravity shit

[Amir_Velaz]

The same issue, guys. Since yesterday maybe… Ultra plan. Right now I can’t use even Gemini 3 Flash Fast and GPT-OSS

[FiguringItOut]

I’m started experiencing the same issue as well yesterday , I am an AI ultra plan subscriber as well. sonnet and gemini 3.1 pro are working for me however

I have been facing the Our servers are experiencing high traffic right now, please try again in a minute. for a few weeks now.

You used to be able to download an older copy of Antigravity(and turn off automatic updates) that didn’t have the update that added this crap, but they force you to a more recent version now, so you cannot even use the older version anymore.

The only solution I have been able to find is going to a less capable model(Gemini).

It is a hard pill to swallow while paying hundreds of dollars a month for the service.

I got sick enough with it that I am currently working on migrating to Cursor and getting the IDE set up as I had in Antigravity.
