Re: Somewhat off topic but...
Maybe call your crap ISP and complain? Backhaul is the cheapest thing to provision. Because turning a 1Gbps link into a 10Gbps link, or a 10Gbps link into 4 x 10Gbps links is not that expensive. And it has gotten a lot cheaper in the last 12 months.
My "crap ISP" has won more awards for customer satisfaction than any other in Aus but they are at the mercy of our former monopoly telco for backhaul in our region. Any other useful suggestions?
