Is the Verisign Timestamp server down?

I was trying to build my setup scripts with Inno Setup these past two days (1 & 2 Jan 2021) and the digital signing was failing. So I contacted Verisign via email and await their response.

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.

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

When using Microsoft's SignTool.exe

Change the timestamping server (-t):

• Before: signcode -t "http://timestamp.verisign.com/scripts/timstamp.dll" (defunct)

• After:    signcode -t "http://timestamp.digicert.com"
