Google Antigravity "High Traffic" Error: Cause, Workarounds & Status

When Antigravity shows 'Our servers are experiencing high traffic right now, please try again in a minute', it returns an HTTP 503 (Service Unavailable). Your request was rejected before processing — this is not a timeout, and not a network error on your side. Either the backend is shedding load because it's saturated, or the system is refusing the request because you've exceeded a usage limit. Both produce the same message, which is exactly why this error confuses everyone.

This is the single most useful step, and almost no other guide includes it. Before trying any 'fix', figure out which problem you actually have — because the solutions are opposite. Run these checks in order:

If the diagnostic above points to a usage/quota limit, you have real options. Google's own troubleshooting guidance points here too: verify your model usage and switch models. This is the 'fix' that genuinely exists for a chunk of users who assume they're hit by a global outage when they're actually just rate-limited.

If status pages confirm a widespread outage and every model fails for everyone, this is Google's infrastructure, not your setup. Antigravity's backend runs on a shared resource pool — all users and plans hitting the same servers. When demand spikes past provisioned capacity (especially during US morning / EU afternoon), the system rejects requests globally. No client-side action provisions more server capacity, so nothing on your end will move the needle.

Earlier in 2026, some users reported that uninstalling Antigravity and installing an older version let them bypass the error for a while. Whatever the exact mechanism, that window has closed: as of around April 2026, users report the same error immediately after rolling back. Bottom line — no version of the client can talk its way past a full server queue or your own exhausted quota, so rollback is no longer worth your time.

Here's an honest pass on the common suggestions, mapped to which problem they could even theoretically touch:

During a global outage, yes — all tiers are affected, and many frustrated Ultra subscribers have said so publicly. There is no reserved priority capacity per tier in the current shared architecture, so paying more does not move you up the queue during an outage. (A quota problem is different — higher tiers get larger usage allowances, so paid users hit per-model limits less often.)

You may not have a one-click fix, but you have real options to keep working:

A lot of paying users — especially on the Ultra plan — have asked about refunds when the service is unusable for hours. Google hasn't published a blanket outage-refund policy for Antigravity, so this is handled case by case. If you want to pursue it, your best path is Google's official billing support rather than the developer forum (the forum is for technical reports, not refunds). Document the dates, times, and the error so you have a clear record when you raise the request.
