Service checks when host is down

well, think about it, if you have service down alerts you may think that 
the service is broken or crashed or switched off. If you see both 
service and host alerts then you know which services are broken and you 
can also immediately see that it is due to the machine being down, so 
you don't waste time trying to remotely connect to it. It's more 
informative.

The problem with host alerts is it is easy to miss what services are 
broken, since you can have many services on one host. If you have, for 
example, 9 things being monitored on a server, and the server goes down, 
you may only be thinking of 5 or 6 services that it hosts, so you would 
not be aware that another 3-4 services are also down.

It's about awareness (and wanting to spam your inbox with more emails 
;-)  ).
