Attack DDOS ?

Bonjour,

Depuis jeudi dernier, ma connection subit de forte baisse de régime et surtout, il m'arrive plusieurs fois par jour de perdre totalement le réseau. Je suis située entre Esneux et Boncelles, et après avoir contacté le service helpdesk, on m'a signalé qu'il y avait un soucis ce weekend... mais en principe ce dernier serait résolut.

Néanmoins mon installation continue à régulièrement être figée, m'obligeant à ré-initialisé le routeur.

En analysant les logs de ce dernier, je constate beaucoup de log de type "DDOS". Il s'agit souvent d'IP tel que Facebook ou Dropbox, qui pourrait juste être liée à des réponses du protocole HTTPS... mais aujourd'hui, alors qu'à nouveau la situation était bloquée... il me semble que cela provienne d'Indonésie (cf log).

Qu'en pense les plus avertis ? Est-ce normal pour utilisateur lambda que je suis d'être la cible d'attaque DDOS, est-ce simplement une mauvaise interprétation de mon routeur, et tout simplement un soucis de réseau chez moi ?
