Is the Verisign Timestamp server down?

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

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

So the timestamp server is no more.

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


When using Microsoft's SignTool.exe

Change the timestamping server (-t):

  • Before: signcode -t "" (defunct)
  • After:    signcode -t ""
