VS Code Marketplace publish blocked by VSID "Concurrency" rate limit for over 24 hours — verify-pat also blocked

We cannot publish updates to our VS Code extension and even a read-only PAT

verification is rejected. Microsoft support seems to be the only way to

clear this, so please help.

Symptom

Since yesterday (2026-08-19), every call to the Marketplace publishing API

fails with:

Request was blocked due to exceeding usage of resource 'Concurrency'

in namespace 'VSID'.

typeName: Microsoft.TeamFoundation.Framework.Server.RequestBlockedException

errorCode: 0, eventId: 3000

This happens for:

  • vsce publish --packagePath <vsix> --pat <PAT> (the actual publish)
  • vsce verify-pat floatinghotpot (a READ-ONLY permission check — no uploads, no concurrency involved)

What we already checked

  1. The PAT is valid and scoped to Marketplace > Manage (created recently, not expired; verify-pat fails with the SAME rate-limit error, not 401).
  2. The block is account/namespace-wide, not token-specific — we tried a second valid PAT with the same result.
  3. Network is not the cause: we tested both direct connection and VPN to Azure — identical error.
  4. We stopped all Marketplace calls for a full day (no retries for ~24h) to let any rate-limit window cool down — the block persists.
  5. The same error even blocks verify-pat, which performs a single lightweight request — so this looks like an account-level (VSID namespace) lock, not a burst/concurrency throttle.

Context

  • Publisher: floatinghotpot
  • Extension: deepseek-harness-web-for-vscode (version 0.2.0 ready to ship)
  • We previously published fine (0.1.0 and earlier); the block appeared without any abnormal burst of requests from our side.

Request

Please clear the account-level Concurrency lock for publisher

floatinghotpot, or tell us how long this lock lasts and what triggers it.

Our users are waiting for the 0.2.0 update (session manager / multi-panel

sessions). Open VSX publishing works fine — this is Marketplace-only.

    Hi @Liming Xie

    Thank you for reaching out with the details.

    The RequestBlockedException on the VSID Concurrency namespace indicates a server-side rate limit lock within the Visual Studio Marketplace backend. Because this error persists for read-only commands like verify-pat even after 24 hours of inactivity, your account concurrency counter is stuck on the backend and requires manual administrative clearing.

    Microsoft Q&A is a public community forum, and moderators here do not have access to internal telemetry or backend databases to reset account locks. To resolve this, please reach out through one of these official channels:

    1. Email the Marketplace Operations team directly at vsmarketplace@microsoft.com with your publisher name (floatinghotpot), account email, and error log requesting to clear the stuck Concurrency lock. This is the fastest route to get unblocked.
    2. Submit a problem report on the Visual Studio Developer Community under the Visual Studio Marketplace topic, which is monitored directly by product engineering.
    3. Open a support ticket through the Azure Portal under Visual Studio Marketplace if you have an active Azure support plan.

    If you found my response helpful or informative, I would greatly appreciate it if you could follow this guide for your confirmation.

    Thank you.
