Any issue with www.cisco.com
Last night I had a maintenance so I use www.cisco.com for testing the network connectivity. But it seems that I'm seeing about 20% packet loss from www.cisco.com. I did same test from various points including my home cable modem connection, which is not my company's network, but I'm getting same result. Are you guys seeing same thing or different result? Is there any issue with cisco.com network? Hyun

I'm seeing roughly ~25 percent packet loss, it varies.

If you are relying on ping and traceroute tests to measure packet loss, then you are coming to false conclusions. ICMP responses are throttled by many, many devices including routers, load balancers, firewalls, IPS devices, etc, etc. - -- ========= bep -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (MingW32) iD8DBQFDHdMFE1XcgMgrtyYRAsjzAKDniJ5MAj+PWxH6vgYaImbJc/9A9wCfdNCx aBMSXJIsAm4NaGvJTVUpIVg= =rKlr -----END PGP SIGNATURE-----

Yet another "Me too!" response. We often use pings to www.cisco.com as a Internet connectivity test from globally dispersed sites. These are typical ploss for ICMP pings. The most likely answer, as others have pointed out, is throttling at the destination. The fact that so many people use www.cisco.com for this purpose is probably why they need to throttle traffic.

Are you guys seeing same thing or different result? Is there any issue with cisco.com network?
