Intermittent Vercel Blob Storage connectivity issues from Spain (ERR_CONNECTION_TIMED_OUT)

Help
1

We are experiencing intermittent connectivity issues with Vercel Blob Storage assets.

Example failing URL:
https://adru7csjaghw8o7t.public.blob.vercel-storage.com/ads/16c3a13f-f547-47b1-bcca-d0e69d98e8d7/51d69af3cca2a349.webp

Issue details:

  • The problem started on May 12.

  • Yesterday the issue lasted around 2 hours and then started working again automatically.

  • Today the issue started happening again around 30 minutes ago.

  • The issue affects all images stored in our Blob storage, not only specific files.

  • The browser error is:
    ERR_CONNECTION_TIMED_OUT

What we already checked:

  • Blob files exist correctly in the storage.

  • Blob store is configured as Public.

  • BLOB_READ_WRITE_TOKEN is correctly configured.

  • The issue happens across multiple devices and networks.

  • Tested from laptop and mobile phone.

  • Tested using different ISPs/networks.

  • Some of our visitors/users are also reporting the same issue.

  • We are accessing from Spain (Madrid region).

Additional observations:

  • Since the issue is intermittent and affects all Blob assets globally for us, this does not appear to be related to a specific file upload or application-side configuration.

  • It looks more like a regional connectivity/routing/infrastructure issue affecting access to Vercel Blob Storage endpoints from Spain/Europe.

Could you please investigate whether there are any networking, CDN, routing, or infrastructure issues affecting Blob Storage accessibility in Europe/Spain?

Thank you.
