Personally I always had a sneaking suspicion that Citylink never released graphs because the actual amount of traffic was tiny. Probably not true but how could I tell?
<obj disclaimer, ancient history, it's been years since I was in the employ of Citylink> For a long time, particularly on WIX, there was a mechanical problem of defining what an exchange port, and identifying IX traffic. People pushed traffic into a single shared vlan, some was transit, some was peering, some was point to point private stuff. A graph of all the ingress data in that vlan wasn't particularly meaningful as a way of describing the peering activity, since it had (literally) hundreds of ports doing things unrelated to BGP. Once the process of draining the swamp was underway - splitting the single vlan into transit vlans per ISP and private vlans for point to point (so that the IX was all that was left in the original vlan), there was a period (of a couple of years) where an aggregate graph of the original vlan would have suggested the amount of exchange traffic was falling. During that period, there definitely was a lack of enthusiasm for publishing aggregate ingress data, since the graph trend didn't match reality (at least, reality as we assumed it to be - we didn't have much other hard data on IX trends).
