ocsp.starfieldtech.com
Starfield Technologies offers TLS certificates. You shouldn't block the revocation checks.

Their root is really strange. ( view-source:https://www.starfieldtech.com/ ). And it is in the Blocklist list

Thinking about whitelisting all ocsp.*

• ocsp.trust-provider.com - root is 404 and in EasyPrivacy list. They have crl.trust-provider.com as well
• ocsp.advance.net - root is in Dan Pollock's hosts file. Redirects to advance.com
• ocsp.certificateservices.eads.com - root is 504 and in several lists
• ocsp.ezoic.net - root domain is clearly ad-driven
• ocsp.geotrust.com - root is about certificates, but is in EasyPrivacy
• ocsp.ca.hsdn.org - root is in many lists
• ocsp.atlassian-app.atlassian-app.eu.tt.omtrdc.net - root domain is clearly ad-driven

Also, ad providers in future could exploit this whitelisting of ocsp.* subdomains. Maybe. Because why not.

So, I am in doubt about such whitelisting.
