Anyone from google? - possible routing loop

Fri Jan 30 15:32:45 UTC 2015

The shaperprobe test program from M-Lab is not working.  The problem
appears to be a routing loop in google's realm.  Emails to m-lab over
the past month were not effective in resolving the issue.

shaperprobe: http://www.measurementlab.net/tools/shaperprobe

64.9.225.153 is server shaperprobe uses.
