Obsolete:Routing problems
French squids
The French squids at 212.85.150.{131,132,133} are experiencing strange routing problems. Some people have absolutely no problem accessing them, some experience huge packet losses and delays. All problems seem to happen between the last hop (212.85.144.6 ) and the squids. These problems seem to be happening on the return routes:

Most problems seem to start occuring once packets travel across glbx.net (Global Crossing) links.
Since non-French users have been taken off the Paris squids, the situation has come back to normal, with no abnormal ping times or delays.
EXPLANATION
Lost-Oasis, the French company that offers us free rack space, pays quite a lot for transit to some foreign networks. Since we're a non-paying customer, they have implemented a rate limiting filter to these destinations.
This explains while it's perfectly possible to ping from these destinations when these countries are not using the squids, and why things go weird once the squids are in use from these destinations.
Lost Oasis has been asked which destinations are affected and for what rate.
