asterisk users - Oct 2005 - One SIP dead, all SIP dead -- sipmedia gone?

I'm having the following recurring problem with asterisk:

When for any reason one of my SIP providers fails to register (i.e.
internet connection dropped), ALL SIP channels fail.  This means that,
for example, when my internet connection is out, none of my internal sip
phones register, and I'm unable to place outgoing calls (through IAX),
or to check voicemail.

Currently (and since yesterday evening), sipmedia.com/myphonecompany.com
is completely off the radar.  No DNS entry found -- not even a
name-server.  They've had this sort of massive failure before, but this
is one of the longest for all I can tell.  While that's a major problem,
it also meant that until I commented out the register =>
sip.sipmedia.com statements, my entire phonesystem was unavailable.

1. Is there any way to get Asterisk to behave less absolute when one sip
registration fails?
2. Is anyone else experiencing the same sipmedia outtage, and/or has
information on when they'll be back?  Tech support seems affected, and
other direct numbers I have go into voicemail.

Never heard of them.  The IP block which their NS1.SIPMEDIA.COM is in is

NetRange:   66.128.0.0 - 66.128.15.255
CIDR:       66.128.0.0/20

and this appears to be off the air.  We have no route listed for this at
this time.  The IP block for NS3.SIPMEDIA.COM does have a route but
traceroutes to deadness.

The parent block containing this one is advertised in BGP right now, but
I see a whole bunch of /24's covering this block as well, and that route
is not covered by a /24 or /23 announcement.  This looks like they are
fully withdrawn at this time. 

I see a slew of withdrawls for that route around 10/21 23:42.

FixedOrbit sees them as singlehomed to Savvis, which isn't having any
problems that I'm aware of, other than this humorous bit:

:-)

I do notice that there seems to be no web site for www.xchangetele.com,
which suggests that possibly they tanked.  If your sipmedia.com was
reselling their services, then it is reasonable to think that they went
along for that ride.

DNS failures are way too catastrophical for Asterisk now. We need to fix
that urgently.

FWIW, I don't see that same issue. I only have one sip provider (and
serveral iax links), but when the sip register fails I'm still able to
complete local and iax calls. This is with cvs-head as of yesterday.

Asterisk handles DNS failures VERY badly.  Make sure your phones and 
Asterisk always refer to devices by IP, not by DNS name.
