Mi lehet ez?

Az imént vettem észre, hogy nincsen minden rendben a hálózati kapcsolatommal.

Egy gyors Counter Strike indítás, azon belül is egy net_graph elég egyértelműen azt mutatja, hogy valami gond van.

A kis grafikon szinte fűrészjelet rajzol. Szerintem DDoS támadás van folyamatban, én arra tippelnék.

Valaki, aki kompetensebb a témában, felvilágosítana?
