What the models said for it

Verbatim evidence the judge attached to positive labels.

“Fully managed Kubernetes with strong SLAs and support.” GLM 4.7 FlashX · Managed Kubernetes · negative prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Avoid: ... niche like Rackspace Spot (auction-based, less proven for B2B)” Grok 4.1 Fast · Managed Kubernetes · direct prompt · hard negative

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Rackspace Spot's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Rackspace Spot, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at rackspace.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
