Vault service is currently broken in production

A SWH user just reported in the swh-devel mailing list that it could not download a tarball that should have been cooked by the vault:

Dear Sir/Madam,
I'm trying to download some repositories, but my request always remains in "status":"new".
I've tried using both the APIs and the web interface, but the result doesn't change.
I'm attaching the curl command I'm using, along with its return.
Currently, I'm making anonymous requests without logging in.

curl -X GET https://archive.softwareheritage.org/api/1/vault/flat/swh:1:dir:4b08ee87eff2025999004c30da9cdf91da60cb44/
{
  "fetch_url": "https://archive.softwareheritage.org/api/1/vault/flat/swh:1:dir:4b08ee87eff2025999004c30da9cdf91da60cb44/raw/",
  "progress_message": null,
  "id": null,
  "status": "new",
  "swhid": "swh:1:dir:4b08ee87eff2025999004c30da9cdf91da60cb44"
}

Can you provide any guidance on the cause?


Thanking you in advance,

Giacomo Corridori

Looking at associated sentry report, it seems the vault cannot connect to the scheduler service.
