Azure Static Web App deployments hanging in polling state — both GitHub Actions and SWA CLI fail identically

Question

Our production Static Web App deployments have been non-functional since approximately 2:00 PM CDT on April 23, 2026. The previous successful deployment is still serving traffic, but no new deployments can complete.

Environment

• App name: hueXX-prXX-wXX
• Resource group: hueXX-prXX-aXX
• Location: XXXXXX
• SKU: Free
• Production URL: prXX.huXXburXXX.com

Removed PII information

Symptoms

The build step completes cleanly — Vite transforms 2,074 modules, dist artifacts generate normally, upload to Azure completes. Then deployment polling runs indefinitely and eventually times out at ~600 seconds with:

Upload Timed Out. Unsure if deployment was successful or not.

Azure Portal then shows the Production environment status transition from Uploading to Failed.

Reproduction — fails identically via two independent paths

1. GitHub Actions workflow (Azure/static-web-apps-deploy@v1) — our standard path, used successfully for 250+ prior deployments over the past several months, typically completing in 2–3 minutes. Multiple commits today all fail the same way.
2. SWA CLI direct deploy (@azure/static-web-apps-cli 2.0.9) from local Windows machine, bypassing GitHub Actions entirely:

   
      swa deploy ./dist --deployment-token <token> --env production --verbose silly
   
   

   Same behavior. Upload completes, polling hangs, times out.

Specific DeploymentIds that have failed

• be0e2820-6813-4dfc-bc8d-d1e9504067ee (GitHub Actions)
• 929a2501-59cd-43b4-b513-45b1e7758c33 (SWA CLI)

What I've ruled out

• Build errors — build completes cleanly in both CI and local.
• Local environment — the CLI path uses a completely separate deployment flow and fails identically.
• Code changes — the in-flight commit is a small UI fix to a dropdown component; nothing architectural.
• Credentials — token is valid, authentication succeeds, artifact upload succeeds.
• Bundle size — 1.08 MB gzipped to 288 KB, consistent with prior successful deploys.

What I've checked

• Azure Status page: no active events.
• Portal → Service Health → Service issues: no active events for Static Web Apps.
• Portal → Service Health → Health advisories: nothing relevant.

Business impact

Executive demo of this application to restaurant ownership is scheduled end-of-business Friday April 24, 2026. Current production (previous successful deploy) is serving and demo-functional, but we cannot ship any further fixes or features until deployments resume. This blocks our entire release pipeline.

What I need

• Confirmation of whether this is a known regional or service-wide SWA deployment pipeline issue.
• ETA if a rollout is in progress.
• Any workaround to complete a deployment in the meantime.

Happy to provide additional logs, DeploymentIds, or diagnostics. Thank you.
