Strange issue -- all hosts down

[Zac]

A couple of things to check, did you upgrade your plugins recently?  Or
changed permisions on check_icmp?  Have you tried pinging your hosts on the
command line of your nagios system to ensure someone didn't put a firewall
in front of you?  Are you running Service checks on these hosts?  Are they
reporting any problems?  Could you also reply with the output of nagios -v
nagios.cfg.
