Is the Verisign Timestamp server down? [closed]

I received an official response from Verisign this afternoon (on 2 Jan 2021):

Thank you for contacting Verisign Support.

This server was deprecated after our authentication services were sold
to Symantec, which is now Digicert. You can find a list of free
timestamp servers online or theirs is now at
http://timestamp.digicert.com.

If you have additional questions, please do not hesitate to contact
us.

So the http://timestamp.verisign.com timestamp server is no more.

At the moment I know of the following alternatives (in addition to Digicert above) which work well:

  • http://timestamp.comodoca.com/authenticode
  • http://timestamp.globalsign.com/scripts/timestamp.dll
  • http://tsa.starfieldtech.com
