It is not a default for an Internet access service. It comes bundled as one of several features in an optional add on service. See https://www.xfinity.com/learn/internet-service/modems-and-routers for details. This is targeted at the average consumer, particularly those that may want parental controls, mesh WiFi, a voice port, and so on - so not really targeted at NANOG list subs like us. ;-) That said, I have an XB7 modem at home and really like it a lot - especially the new AQM feature that dramatically lowered working latency. > That means that anyone whose site happens to get miscategorized by them gets > the added costs of dealing with the user complaints instead of Comcast having > to bear the costs of their error. As my other reply noted, this service uses a bunch of 3rd party services and it is those 3rd parties that maintain the lists (a la anti-spam and anti-phishing email list vendors). So if an IP/FQDN/URL happens to be on "our" list it is very likely getting filtered/blocked in a lot of network places because it is on a well-known independent list. BUT, how do we know that was even the case here? Do we have a traceroute or a screen shot of an error or block message? We seem to have concluded it was blocked by a content filter but what technical evidence do we have (that can help troubleshoot)? I know you are not the OP (it is Chris) - but I'd love to know more technical detail and I am in communication off-list with the OP (along with my colleague Tony Tauber, who was the first to reach out to Chris 1:1).
