So, it's probably a multifaceted problem:
1) acls (router)
2) firewalls (host)
3) route acceptance (routers)

Some can be audited 'easily' some are 'set and forget' (or forgot :( )

Ping might just be dropped to destinations, before any idea of 'ip space'
filters (think www.sun.com filters). You really have to test with the
protocols your main user base might be using (http/https).
