[AusNOG] Pipe Brisbane Peering Exchange traffic dropoff

Thu Nov 12 13:44:24 EST 2009

That IP address I certainly don't see via Peering L Strange that when I
resolve download3.vmware.com we get a different IP which 'is' advertised
locally.

We are seeing download3.vmware.com via Equinix Peering although the IP
address appears to be different:

Trace complete.

I can see routes over PiPE but our BGP is preferring Equinix Peering because
we have so much of it J

Lucky you - for me it ends up across peering in Tokyo.   Akamai do strange
things - I suspect if you understood what was happening your head would
explode.
