ip sla

i'm running ip sla for isp failover/failback on an isr 1900 with below configuration:

track 1 ip sla 1 reachability
 delay down 180
ip sla 1
 icmp-echo 4.2.2.2 source-interface FastEthernet0/0
 timeout 500
 threshold 250
 frequency 1
ip sla schedule 1 life forever start-time now

 

When i do a cable pull test(pulling cable from isp1 interface and put back)failover/failback works fine.  Sometimes, during actual outages, it fails over fine but does not failback.  Does running icmp-echo instead of another method effect this?  Is it better to make the icmp target the isp modem instead of a dns server on the internet?
