Re: Weekly Routing Table Report [In reply to]

Yup, the CIDR Report gets its feed in Australia...

I get my BGP feed from APNIC's router in Japan - and at the time it
grabbed the dump, the BGP table stopped at 190.55.80.0/21. Not sure
what's going on, looks like the ssh session just hung, but then
terminated normally - so the script's checking for hung sessions or
early disconnects didn't catch it.

Sorry folks...
