Yhteys poikki

Yhteys katosi eilen illalla puolen yön maissa, kesken käytön. Ensin lakkasi DNS toimimasta, mutta DNS-palvelimet vastasivat vielä hetken pingiin, tosin ensimmäisen vastauksen saamiseen meni useita sekunteja. Sitten käynnistin routerin uudelleen, sillä tuloksella että se ei enää saanut DHCP:llä vastausta siltaavan ADSL-modeemin yli. ADSL-modeemissa (Zyxel P-660R-D1) palavat kaikki asiaankuuluvat valot (Power, Ethernet ja DSL, Internet ei pala siltaavassa tilassa). Modeemin uudelleenkäynnistys ei muuttanut mitään. Modeemin oma ATM-loopback testi OK. Uskaltauduin tekemään vikailmoituksen, vaikken toisella modeemilla olekaan testannut, koska ei huvittaisi kovin montaa päivää odotella netin palautumista. Tarkistin vielä, että laskutkin on maksettu ja kai Soneralta huomautus tulisi kuitenkin ennen netin katkaisua?

Alla modeemin debug-dataa:
