Oz is missing
Unless you have an interest in submarine cables you probably wouldn't know that a major trans-Pacific segment, operated by Souther Cross Cable, makes landfall in Hillsboro, Oregon. SCC's VP of Ops has confirmed that hurricane-strength storms and flooding have wiped out the carrier's Oregon cable route and halved its bandwidth between Australian and the US.
We've seen much of the net unreachable due to flapping BGP sessions causing route dampening on a lot of address space in Australia, so if Oz is unreachable where ever you are, this is probably why.
