Outbound traffic from 208.89.136.0/22 going from L.A. to London?

I'm seeing some weird routing outbound for *some* destinations.
Testing from 208.89.139.252.

google.com resolves for me to 74.125.239.112 and the outbound path is
fast and appears to stay in the US.

yahoo.com resolves for me to 98.138.253.109, but the outbound path
goes through Savvis London, then to BT, then to Yahoo.

Traffic served by Akamai appears to be fast and stays local (i.e.
tested to www.apple.com).

A call in to Savvis got attached to master ticket 4828052, which is
for "large packet loss". Describes the symptom, not the cause.

Is there anybody who has more info? Anybody who's a Savvis customer
who sees the same weird outbound routing? Or are we the only ones?
Feel free to traceroute to 208.89.139.252 to try and duplicate these

We are seeing issues on our Savvis Internet connections in New York to
users in London and Sweden. Not many details yet, just seeing slow and
sporadic connectivity.

The issue was seemingly fixed about 30 minutes ago, and has been
confirmed to be fixed by multiple parties. Many thanks for the
response Vincent. Have a fantastic day!
