I, on the other hand, don't understand why you are using fork() at all.

use strict;
use warnings;
use 5.010;

use List::Util qw{ shuffle };

my $interval = 2;   #seconds
my $total_time = 1;   #minutes
my $num_checks = ($total_time * 60) / $interval;

my $start_time = time;

my @status = ('up') x 9;
push @status, 'down';   #1 in 10 chance server will be down


$| = 1;

MONITOR_STATUS_LOOP:
for (1 .. $num_checks) {
    my $result =  (shuffle @status)[0];

    say $result;
    my $elapsed_time = time - $start_time;
    say "time left: ", $total_time * 60  - $elapsed_time, " seconds";

    last MONITOR_STATUS_LOOP if $result eq 'down';
    
    sleep $interval;
}

say "on with the rest of the script";

--output:--
up
time left: 60 seconds
up
time left: 58 seconds
up
time left: 56 seconds
down
time left: 54 seconds
on with the rest of the script
