I'm talking about actual unmetered where you pay for a dedicated amount of bandwidth, e.g. 1 Gbps / 10 Gbps / 20 Gbps. 10 Gbps usually goes for about $1k-$2k/mo in the US. This is how colo facilities have operated for decades.
10 Gbps fully saturated delivers about 3300TB for that $1-2k/mo, versus the $22k/mo you'd pay AWS for the same.
I'm absolutely not talking about the "unlimited bandwdith" bullshit that discount hosts offer.
If your project gets featured on CNN and your bandwidth goes up 20x can these colo arrangements automatically scale up your dedicated bandwidth? I ask because having an outage when you get your first big break can cost you WAY more than your bandwidth bill ever would...
