Shell Programming and Scripting

This is my first posting here, I haven't found exactly what I'm looking for anywhere else so I'm hoping you all can help. I have a portion of script here that needs to ping two servers, then return whether they are up or down (somehow), and then echo that information. Here is what I have so far. It does echo up/down, but the information doesn't change regardless of the ping success.

Code:

SERVERUP=1
SERVERDOWN=0
ping -q -c1 192.168.1.11 > /dev/null; ping -q -c1 192.168.1.10 > /dev/null
if [ $? -eq 1 ]
then
        SERVERUP=$((SERVERUP+1))
else
        SERVERDOWN=$((SERVERDOWN+1))
fi
 echo "Servers up: $SERVERUP Servers down: $SERVERDOWN"
