Affected users will see the above symptoms, often with timeout or host not found errors.
Underlying cluster health is unaffected, including Atlas search queries.
Additionally, Vercel users may not be able to get directly to Atlas from within Vercel. As a workaround, users are encouraged to login directly to Atlas at cloud.mongodb.com
