AVHJÄLPT: Stort avbrott i Ubbhult fiber och närliggande nät

20.50: Hela nätet går ner. Som många har observerat lyser WAN-lampan på mediaomvandlaren, vilket indikerar att vårt nät fungerar, men att noden inte har kontakt med omvärlden. Vi har också fått rapporter om att Härryda stadsnät och Landvetter ligger nere.

22.22: IP-Onlys driftinformation säger att det skett en större incident i Göteborg. Det verkar som att flera nät blivit bortkopplade under reparationsarbetet. Beräknad klartid: 02.00

02.50: Konstateras att nätet nu är funktionellt igen.
