Network restart script does not complete as a cronjob

I have this simple script on crontab (root): (centos 6.5)

if ! ping -c 1 172.20.1.1; then
echo "NOT OK" >> /root/log
ifconfig eth3 down
sleep 5
ifconfig eth3 up
else
echo OK >> /root/log
fi

The script works fine if I run it from directly from terminal and restarts the interfaces but not when run through crontab. I wanted to see if the crontab is actually running as expected and put the echo lines and I'm 100% sure the script is running because I see the OK and NOT OK lines on the log.

What do you think is wrong with this?

hint: crontab has a much limited default PATH environment variable – Dan Oct 28 '15 at 07:13
Thanks dan, just putting /sbin/ prefix to ifconfig fixed it. – user2629636 Oct 28 '15 at 11:29
You can also put in crontab before job definitions a line like PATH=your:path:definition:here to avoid putting full paths into scripts – Dan Oct 28 '15 at 14:34
