I think Perl is still more popular even today than Python as a sysadmin language. Late 2000s it certainly was. Maybe Google was different, but across the industry more widely Python was barely used, Perl was used everywhere.
My experience:
Sysadmin-driven companies (typically Sun-based) often used Perl.
Developer-driven companies used other languages running on cheaper X86 Linux.
