Complimenti, ma ho una domanda!

[gokugt]

Salve Gandalf, la mia non era la puntualizzazione di un problema riscontrato, e già che ci sono preciso che il mio sito non è niente di che ... trovo soltanto strano che dai test che ho fatto, Cogent sembra non venga sfruttato, mi riferivo a questo quando ho scritto che la maggior parte delle route vengono instradate via retelit, ma a quanto pare invece entrambe le vostre linee hanno lo stesso carico.. trovo però ridicolo che da rete Cogent si vada a finire poi su Retelit, lo si potrebbe interpretare come una policy di routing poco efficace..

Altri esempi..

etc.. etc..

Sembra quasi che del link Cogent se ne possa fare a meno...almeno per il traffico in entrata, ad ogni modo è solo una mia considerazione personale.. e il vostro servizio continua ad interessarmi.

Grazie.
