a colleague and I are pinging the same website from different locations (geographically, we are about 30 miles apart, both pinging a server about 1500 miles away). Pinging at 15 second intervals. Oddly, I will show a whole spurt of packets dropped by the target server during a particular period, indicating server difficulties, but my colleague may not show that at all. Why would this be? We want to reliably know when the server is having problems, but these differences make it difficult to be sure...
