Le routeur de France Telecom annoncé à Hansenet les IP d'OVH sur Decix !?
Ce qui fait que les visiteurs de Hansenet avaient un routage très bizarre.

Nous avons contacté Hansenet. Suite à ça, le probleme a été resolu sans
aucune explication. Nous avons vu un routeur se coupait sur Decix:

On pense que ce routeur là a été à l'origine du probleme. Une
mauvaise configuration du routeur ou le routeur en lui-même qui
fait n'importe quoi.

Le probleme est resolu.

Le probleme continue sur certaines IP de Hansenet.

En gros, le routeur d'equant fout le bordel malgré le fait
qu'ils ont coupé les sessions BGP. Nous avons telephoné à
Opentransit (en Inde) pour leur signaler le probleme. Sans
resultat.
