Pretty much any colo or dedicated/bare metal provider. $0.07 to $0.12 per Mb is the going rate for most carriers at any appreciable volume, and even the higher end carriers are less than 3x that.
To be fair, big tech despite their massive volume pay much higher rates than small networks because the carriers charge them enough to fully cover their costs to build out their networKs, while they make all their profits from selling their excess capacity to the little guys for pennies on the dollar.
At $0.07/MB, your talking over $70K to transfer a TB. Am I missing something here? Because I'd say $70k is quite a bit more than "a couple of dollars" the GP mentions. (No, I dont deal with cloud pricing at all, so I'm a little perplexed here)
Network at the wholesale level is always measured in Mbps using 95th percentile, not in data transferred (average sustained, equivalent to 50th percentile because we're talking about 5 minute samples of interface counters over the course of a month). Note I used a small b in Mb. Depending on the variability of traffic patterns, that usually works out to be on average ~200GB* transferred per Mbps of 95th percentile over a period of a month. Meaning a TB would work out to about $0.35.
*A long, long time ago, I looked at about 1000 co-location customers' MRTG stats and compared their monthly 95th percentile Mbps to their average sustained data transfer in GB, and something like 90% of them were between 150GB-250GB per Mb and 98% of them were between 180GB-220GB. Many people assume 324GB which would require their traffic to be perfectly flatlined throughout the month, which obviously rarely ever happens.
