Working in the field of networking I can say it's highly unlikely that Cogent is performing traffic shaping specific to Panic traffic. That's a ton of changes to a ton of hardware with a risk for screwing things up that just isn't worth it. Cogent isn't going to go to those lengths for a client that has a single connection and hosts a small / moderate site. Beyond that: the connection that Panic has to Cogent is most likely through the data center they're colocating with, not a direct connection to Panic equipment. That's not for certain, it's entirely possible that Panic paid for a drop from Cogent; however I'm guessing that's not the case.

What I find odd is that they would colocate their hardware in a DC with only a single provider. The company I work for has four transit providers so as to ensure uptime / reliability (don't get me started on how often we experience unplanned maintenances from our upstream providers). Seems like Panic may want to consider a different host for their colocation or examine (provided they're dealing with Cogent directly) a secondary ISP.

I think it's extremely unlikely the provider only has cogent. More likely is the fact that the link between the provider and comcast preferred cogent - which panic would have no way to change.

That's not true. panic.com has an A record (and www is a CNAME to @) that points to an IP address that's not PI and advertised only as part of 38.0.0.0/8, obviously, only from Cogent.
