Re: app6 up

Answering myself, ping times from app4 (phx-Arizona), app5.vpn 
(tummy-Colorado), and app6.vpn(telia-Germany) to db2(phx-Arizona)

[toshio@app4 ~]$ ping db2
PING db2.fedora.phx.redhat.com (10.8.34.120) 56(84) bytes of data.
64 bytes from 10.8.34.120: icmp_seq=1 ttl=64 time=0.249 ms
64 bytes from 10.8.34.120: icmp_seq=2 ttl=64 time=0.285 ms
64 bytes from 10.8.34.120: icmp_seq=3 ttl=64 time=0.764 ms
64 bytes from 10.8.34.120: icmp_seq=4 ttl=64 time=0.280 ms

[toshio@app5 ~]$ ping db2
PING db2.vpn.fedoraproject.org (192.168.1.19) 56(84) bytes of data.

[toshio@app6 ~]$ ping db2
PING db2.vpn.fedoraproject.org (192.168.1.19) 56(84) bytes of data.
64 bytes from 192.168.1.19: icmp_seq=1 ttl=64 time=196 ms

So each request from an app server in phx to the database or to another 
app will be 200x faster to set up than from an app server at tummy and 
nearly 1000x faster to set up than telia.  If we deploy apps at telia it 
will be essential to minimize the number of requests if we want to keep 
things fast.
