Hi List, FYI. We have been using CentOS 6.4 and have 2 vpn/gre tunnels to separate cisco rtrs using ospf. with kernel 2.6.32-358.23.2 We have upgraded to 6.5 bit using kernel 2.6.32-431.5.1 and the exact same configuration scripts for our vpn/gre tunnels.

What can I do to UNDERSTAND why, periodically, I can't reach www.centos.org (but everyone else can)? Every few months, http://www.centos.org just drops off for me and for me only. It's not the web site, because I can reach it via a proxy (e.g., TOR browser bundle) and other tests show it to be alive (e.g., http://www.downforeveryoneorjustme.com/centos.org or
