Yes, but we assumed it was because of the new IP addresses they've
recently introduced.  We're updating our firewall rules to deal with the
changes.

Starting some time yesterday, <JID>@gmail.com users started to appear
unreachable to some of our users.  Restarting our XMPP server brought
them back in the roster, but we are unable to send messages to anybody
in GMail-land. Eventually, we get timeout messages.  Checking the hosts
in the SRV record for  _xmpp-server._tcp.gmail.com. I see:

========
_xmpp-server._tcp.gmail.com has SRV record 5 0 5269
xmpp-server.l.google.com.
_xmpp-server._tcp.gmail.com has SRV record 20 0 5269
xmpp-server1.l.google.com.
_xmpp-server._tcp.gmail.com has SRV record 20 0 5269
xmpp-server2.l.google.com.
_xmpp-server._tcp.gmail.com has SRV record 20 0 5269
xmpp-server3.l.google.com.
_xmpp-server._tcp.gmail.com has SRV record 20 0 5269
xmpp-server4.l.google.com.
========
xmpp-server.l.google.com:5269/tcp is reachable
xmpp-server1.l.google.com:5269/tcp is reachable
xmpp-server2.l.google.com:5269/tcp is reachable
xmpp-server3.l.google.com:5269/tcp is down
xmpp-server4.l.google.com:5269/tcp is down ========

The IP addresses I see are as follows:

========
xmpp-server.l.google.com has address 74.125.155.125
xmpp-server1.l.google.com has address 74.125.155.125
xmpp-server2.l.google.com has address 74.125.47.125
xmpp-server3.l.google.com has address 74.125.45.125
xmpp-server4.l.google.com has address 74.125.45.125 ========

My XMPP server (an out of date, but otherwise servicable jabberd-2.1.19)
appears to see all of these addresses, but shows a boat-load of timeouts
to 74.125.45.125.  It is not clear that *any* of our outbound messages
are getting through, although we can *receive* messages from @gmail.com
users.

Any thoughts?  Is anybody else having trouble talking to Google?

                        Thanks,
                                    /Chris
